If you frequently pass your crush in the halls, plan on giving him the note during that time. You won’t have too much time before you have to get to your next class, so you won’t have to worry about standing around and talking awkwardly.  If you’re too nervous or anxious to pass the note yourself, give it to a friend to pass on. Make sure you choose a friend that you trust, just in case they decide to read the note themselves and tell others what it says. You could also give him the note in class. He’ll probably be thrilled to have something to do (other than focusing on the lesson and studying, of course). Just make sure it doesn’t fall into the wrong hands. You don’t want your teacher to find it and confiscate it, or worse, read the note out loud. If you don’t want to give the note directly to your crush and you feel weird asking someone else to do it, slide the note through the slots in his locker. Just make sure you’re putting the note in the right locker. If you feel that you couldn’t possibly give your note at school, try sending it through e-mail. Some people believe that e-mail is not romantic, but that’s actually not the case. As long as you’re being honest and sharing your feelings, your crush won’t really care how you send them over. You can also send your note as a text or Facebook message. Whatever medium you feel most comfortable using, do that. If you’re absolutely convinced that you couldn’t possibly send your crush a letter with your name on it, try leaving your name off. Your crush won’t know who his secret admirer is, but some people like a mystery. Just know that if you want to actually pursue a relationship with your crush, you’re going to have to come clean about it eventually.
