How to Be Aloof
To be more aloof, keep your conversations brief and limited to surface-level topics like work, weather, or sports. You should also avoid sharing details about your personal life or asking questions that would encourage a deeper level of interaction. Additionally, exit the conversation as soon as you can by making up an excuse such as "I have to get back to work. It was good to see you.” Then, make an effort to look busy by not responding to calls and texts right away and declining invitations to socialize.
Reduce your participation in conversations. If you see people conversing in a group, don't approach them. If someone tries to strike up a conversation, respond politely, but keep the conversation brief. Make a specific excuse to exit the conversation. Say something like, “I need to run to the bathroom” or “I have to get back to work.” Tell the other person it was nice talking to them to wrap things up. You could say, “Well, it was good to see you.” Keep conversations superficial when they occur. Being aloof is all about seeming disinterested, so don't get into the deep stuff during conversation. Stick to surface-level topics like work, weather, current events, and sports. Avoid sharing details about your personal life and don't encourage other people to do so. Don't ask questions. Asking questions keeps the conversation going and shows you're interested in the other person, encouraging them to share more. Appear calm and unruffled. An important part of being aloof is showing little emotion. Even in tense situations, you should do your best to remain cool, calm, and collected. If your aloofness is directed towards a specific person, try to think of your interactions like a science project--interesting, maybe, but with no emotional involvement. Take a few deep breaths if you're getting worked up. Excuse yourself from the situation if things feel like they're about to boil over. If you can't calm yourself down on the inside, make sure you look calm on the outside. Keep your facial expression neutral, relax your shoulders, and unclench your fists. Make it seem like you’re busy. Even if you aren't that busy, you should make an effort to look like you are. Don't linger after work or stop for a leisurely chat at the water cooler. Don't respond to calls and texts immediately or accept invitations right away. Decline at least some of the invitations that come your way. If you don't want to cut people off cold turkey, you can gradually spend less and less time with them. Don’t be rude. Being aloof doesn't mean being rude. It means appearing emotionally detached and uninterested. You can be polite and aloof at the same time--in fact, you should be! When someone talks to you, acknowledge them at the very least. Ignoring someone completely is generally a no-no. Date or flirt with other people. Pretty much all of the general advice applies to exes, but there are some specific steps you can take to be more aloof around exes, too. Don't hang around them all night giving them longing stares and puppy dog eyes. Get out there and talk to other people. You may even get a date or two. Rebound relationships can actually help you move on. Just make sure you feel ready. Limit physical contact. Physical touch is a way to express affection, which you definitely want to limit in your efforts to be aloof. Avoid all forms of touching if you can, including hugging, holding hands, kissing, and sex. Go to other people for help. It may be tempting to call up your ex when you're feeling emotional, but don't. Reach out to other loved ones for help. Sharing your deep emotions with your ex hardly looks aloof. Try to let go of anger towards them. You may be harboring some deep-seeded anger towards your ex. Being aloof will be much easier if you let that anger go. Try to forgive them for any past wrongs or hurts. When negative thoughts about your ex pop into your head, counter them with positive thoughts. Address the thought “I can't believe he left me,” with one like, “It's better off this way. I deserve someone who respects me and treats me right.” Focus on the positive things in your life, like your amazing family and friends. View your relationship as a learning experience. Think about how you can apply the lessons you learned to future relationships to make them stronger and happier. Use aloofness as a last resort to deal with conflict. If you have a fight with a friend or coworker, try to talk through the problem first. Being cold and aloof can permanently damage a relationship, so make sure you're ready to cut off contact before giving them the cold shoulder. Be aloof to distance yourself from toxic relationships. Aloofness can be useful--and even necessary--if you need to protect yourself from a toxic friend or ex. That's because aloofness allows you to limit your emotional involvement with people who hurt you in the past. Use aloofness at work to maintain focus and avoid drama. Aloofness can be helpful if you need to emotionally distance yourself from co-worker drama or have a stressful job that calls for intense focus. However, in more social jobs that require teamwork, it may not be the best idea. Don't be aloof towards your boss unless it's absolutely necessary. To keep your job and have a good work experience, It's important that you stay on friendly terms. A little bit of aloofness at work can help you buckle down and meet necessary deadlines.
