There is nothing wrong with liking someone. What is wrong is liking someone who doesn't like himself.

Do you think the sourest feeling is jealousy? No, the sourest feeling is that you have no right to be jealous.

It's not that others don't care about you, but that you take this person too seriously.

Liking you is my own business, and you have no right to stop it.

If you can't forget him, don't forget him. True forgetfulness requires no effort.
