Yes. And, "Are you all teenagers??" when posters find themselves dealing with unpleasant situations that are not of their creation.
I posted a couple of years ago about an unpleasant situation my partner and I found ourselves in with a mutual friend.
I got some really good advice and some very prophetic warnings about how her behaviour might change/escalate with a sadly predictable outcome.
I got loads of, "You all sound like children!", "How old are you all? 15?" and "Grow up!" type comments.
Her behaviour was pathetic/immature/childish etc but having been put in the unfortuante and uncomfortable position of having to deal with it wasn't!
Oh, and all the smug 'Not My Nigel' type comments from women who are so certain that their partners would never cheat.
I don't believe that my partner would. I wouldn't be with him otherwise! But would I ever be so naive as to proclaim he never would? Of course not.
None so blind as those who will not see often springs to mind...
