Don't meet cute unless your makeup supports it
One thing that really gets my goat when I'm online is that there're always one or two creeps who love hassling me in various ways. For example, one will say, after I've shared something on Facebook having to do with our lousy economy, "Oh, then I guess you're for raising the minimum wage by [write in the hourly amount]." And I'll fire back with something to the effect that hell no, I'm not for it, and why the hell does he think so? Almost always it's a dude who does this, a dude who is probably in his teens or twenties and almost certainly under the age of 22, and the tone makes it clear he's trying to put me in my place.
