AIBU to suspect everyone knows someone 'outspoken'.
Those people who complain about everything, have to pass critical judgements on everybody, nothing's ever right for them, and worst of all they pride themselves on calling a spade a spade (but don't like it back).
I've noticed the people around them though seem to bend over backwards not to upset them, (although it's futile because they're never satisfied with anything) it's like they can't bear the thought of catching the difficult persons negative attention because this is much worse than telling them they're out of order.
Maybe it's something to do with wanting the persons approval?
Or is this what you do if you want the quiet life?
