I'm at the point where most of those FB group posts drive me nuts. There is a whole category that really shouldn't annoy me, but does: it's those "she does gymnastics every where!" posts. The first type are photos of a girl doing a handstand in the middle of a supermarket or something, and all I can think is "Tell her not to do that. It's not an appropriate place for gymnastics...", the second type is "This is how a gymnast eats cookies/watches tv/does homework" etc. with a picture of a girl in a split or whatever while she's doing the activity. They are completely harmless posts, but the "my kid is so dedicated to gymnastics she never stops!" bit gets to me.
Of course, I should probably just leave that FB group!
