Those folks on Facebook are always coming up with new ways to get a bunch of people to do something as a group.
We've had the "bra color for breast cancer" thing where you are only supposed to post what color your bra is (without any explanation other than posting the name of the color) and similarly the "purse placement" where you list the place in your house that you keep your purse (both of which I managed to be as sexual as possible by answering "nude" to the first one and "well, I don't like big ones, so I usually just go without" to the latter).
Today was "Wear Purple Against Homophobia." With all the lesbians I know, I'm surprised there weren't any "purple-people-eater" comments, but maybe I'm the only one with that sick of a mind.
All four of my family members wore purple, but what surprised me was how many of my friends - married, single, gay, straight, young, and old - did the purple thing, too. I have amazing friends!
