OMG, here's another thing in those "You Grew Up In" / "Do You Remember" Facebook groups that makes me want to throw up: the number of posts ending with, or just saying only: "Good times" - or, for variation, "Great times" - just after someone has reminded the person of something they're suddenly finding very nostalgic about.
Now, on the face of it, there should be nothing wrong with saying that. But it's the folksy aspect of the expression, and the way I generally hear people saying it, that I react to. Not to mention, of course, the absolute overuse of it in the first place.
This, for your reading pleasure, has been a rant. Not a rave.
