"I think this is wrong. People shouldn't be afraid to express themselves or self-censor."

Sure, Doctor Casey, sure. Why don't you start by telling your friends exactly what you think of their new haircuts? Tell your SO that his/her cooking sucks. Tell random parents you meet while out and about that their children are ugly. Oh, and next time you don't feel like going into work, just tell your boss that instead of lying and saying that you have a cold.

I'm sure they'll appreciate your honesty.
