Hell is knowing how you feel about someone and not being able to tell them. Hell is knowing they feel the same way back, and are fighting it, not because they don't want to, but because it would make things too hard to deal with, even though the idea is attractive to them. Hell is understanding all this, top to bottom, forwards and backwards. Hell is having it shoved in your face.
I know I'll probably get shit from a person or two about this (and you know who you are...). Do me a favor. Don't.
