Ooh, roadblock. Well then, pull one of my favorites: Lingering in class to accidentally bump into him at the door.Because I'm such a wholeheartedly good person who doesn't have techniques to do this.Just make an excuse to talk to him.(Out of curiosity, what class is it you share? I won't post it here, just want to know.) ~B
If you really like this person, you'll make an effort to go get them to notice you. Don't suddenly barge into his life, sit with him at lunch, and go out with friends and invite him. Gradually work your way there. When he mentions an interest, show interest! Say, "Oh, wow, that's really cool!", even if it's out loud to the whole class. Even better, if he looks at you, smile! It's especially great when you're in class and there's a discussion going on, since you have an excuse to talk to him. Eventually, you guys will become close and things will go on from there!
