It's awkward when you are talking and you accidentally blurt out a piece of information that they never told you and that you found out by searching thoroughly on their Facebook or whatever website, amirite?

I've had that happen so much...it's awkward, but half the time they just assume that they've told me before but just don't remember

It really shouldn't be, since they put up that information for everyone who is their friend to see, but it is.
