Expressing your feelings for someone you care about is something very tough to do, especially if the feelings make you feel like a fool. You can't keep them in your head no more, but you're too scared to open up. You are stuck. If it's someone you deeply care about you're scared to fail them. If it's someone you love you don't want them to see you differently.
But it's different when it's someone you don't specially give a shit about, right? You no longer care if in their eyes you are done or what they think. It's like they are noone to you.It's important to know with what type of person you are talking to. To which category in your mind they fall, so you dont hurt them or yourself.
