I'm not talking here of the horrible stuff, the racism, etc. I'm talking of the "someone said this to me, how rude, especially given that I'd already done this for them"...
My parents have a ledger book of offences "we invited them last time, so we're waiting for an invite from them", etc, etc.
I just think life is far too short to be worried about trivial, minor things that we could take offence at. Ok, so this would eliminate about 50% of the AIBU threads, but so much of it is oh so trivial
