"happiness at the sake of another isn't happiness."
whenever i used to read that quote, i thought that it meant you couldn't be happy if you got that happiness by making fun of somebody else. i don't know, that's just what i thought when i heard that quote.
but today, when i was thinking about it, i decided that maybe it meant that when you rely so much on some other person to make you happy, then you truly aren't happy. because people let you down. so when you aren't happy because of something that's happened with the person who "makes you happy", were you truly ever happy in the first place? the only person we should ever rely on for happiness is God, because He has given us every reason in the whole world to be happy.
