For the love of all that is holy, if you're going to post in AIBU then be prepared to be told you're being unreasonable. That's the whole point of the board.
Don't get bitchy and argue the case, post it on a different sodding board. There's been a good couple today alone (yes I spend too much time here!) with the OP constantly arguing their stance. Nope, they're being unreasonable. Suck it up, learn and move on!
