I got a late invitation to a 40th being held next Friday night (newish friend from dd's school). It's a dinner/dance black tie affair set at a posh London hotel. My immediate reaction was "no appropriate clothes" since it's been so long since I went to a formal event. Next reaction is that I won't know anyone there (other than guest of honor and her husband), and will it be awkward going on my own. Honestly don't know if I'm making excuses because I'm not that interested, or if I'm reluctant to come out of single mum hibernation...
