Making eye contact is an easy and subtle way to let him know you like him. Make the most of your opportunities to look him in the eye. For example, if he says hello to you, look him in the eyes while you say hello back. You can act a bit coy by dropping your gaze, then looking back up at him with a smile.  If he makes eye contact back, chances are he finds you attractive. Try to hold your gaze with him for one to two seconds. Don't stare though! See how he responds––does he smile back, look away or just stare vacantly? Try to gauge his willingness to interact with you. . You might be too shy to come right out and say, “I like you.” If this sounds like you, you might want to hint at your feelings instead of putting your feelings on the line. However, be aware that he might not pick up on your feelings if you’re not outright. You can hint your feelings by saying something like, “I really like spending time with you” or, “It would be fun if we were lab partners.” If you’re shy, it might be difficult for you to go up to the guy, especially if he’s around other people much of the time. Texting can be an easier way to flirt and interact with him without having to worry about awkward pauses or not knowing what to talk about. If you’re texting back and forth with him, use the opportunity to slip in some hints.  Just talking to him over text shows interest. If you want to go a level up, say, “By the way, I think you’re cute.” You can even come right out and say, “I like you” over text once you build your courage. Maybe going up to him and saying that you like him might overwhelm you or fill you with fear. If you see the guy at school (or out of school) regularly, you might want to slip him a note. This way, you won’t have to stumble over your words or ‘blank out.’ if you write a note, you’ll also be able to write a few drafts before settling on one you like and are ready to give to him.  Start by giving him a note and see if he writes back. If you pass a couple notes, you might want to tell him you like him in the next note. Spend some time writing your note and deciding what to say. You might want to make it short and sweet or lay out your feelings. It’s up to you what you want to say in your note, just make sure you tell him you like him. If you want to show him you care but just cannot get yourself to come out and say it, send him something and sign it from a secret admirer. Send him a favorite food (like hot sauce or chocolate) or something you know he’ll like. Send a card and simply sign it, “Your secret admirer.” If you send him something from a secret admirer, try to ask him about it and see how he feels. You will likely need to tell him at some point it was you.
Catch his eye. Hint toward your feelings Text him. Write a note. Send him something from a secret admirer.
