I've not been on Mumsnet very long and have been struck forcibly by the number of messages starting with AIBU? (In fact the acronym was new to me - I had to look it up). It seems we constantly want reassurance from others that we are on the right track, behaving well and not (god forbid) being unreasonable. I can't claim to be immune from this myself but I think it's worth thinking about why we do this. Where is it coming from? Is it a lack of self-esteem or confidence? or do we just like sharing experiences and being validated?
