£150 for a night in London plus money for drinks and an outfit for the 'theme', I really don't like the person who is the hen and can't bear spending longer than half an hour in their company before we both start getting snippy and that's when we're sober, we're diabolical when we're drunk!
To add insult to injury, it's my sister who is getting married and family expectations are that I go and that she invite me. So AIBU to either state outright that I don't want to go or create some kind of excuse like our pet llama Jeff ran away or we had a family of ants set up home in the kitchen and we're helping them get a mortgage....
