Can I get away with mentioning any of these? Because my goodness have I completed #090 before. A lot. Often. In spades. Though, were they faux pas as much as people being overly sensitive? Are those things one and the same?
There was one "friend", not too long ago. I committed a faux pas in that I didn't agree with the friend. Their actions were ridiculous, but while other friends listened to it I had the gall to point out that rather than complaining, maybe the friend should do something about it? A violation of accepted friend and social norms! A FAUX PAS! Said friend has not spoken to me since. Though, has complained about me.
Apparently I was once "glaring" at the former friend and generally being nasty. I should point out that I need glasses.
My glasses are nicer than that though.
So there was no glaring, I am just blind with anything more than five feet away from me without them. And I wasn't wearing them at the time. So there was no glaring at the former friend, because I didn't even notice them in the crowd. But hey, after my horrid faux pas I was public enemy #1 to them.
