People who are sad are pathetic. People who feel too much are scary.
Feel only happy feelings. And never complain. That's not sexy.
Also, don't love too much. It makes you come off as needy.
And needy's not sexy either. It makes you look like a loser.
And nobody wants a loser.
So you cry on the inside. Pretend you're happy. And strong. Invincible.
The circle of life, eh?
