bad thing to doI hate when people tell me to smile. Sometimes, it's not a big issue, but when the same person says it over and over, it's the most annoying insult ever. Or if they say something demeaning, such as, "Do you have down-syndrome? Smile! ::proceeds to use fingers to mock a smile:::"
And saying someone is being too quiet or "mute" is quite possibly even worse.
Real good way to get on my bad side.
