Do your own thing, Lizzy. I've always found the only one I can rely on is myself, and even then not all the time! Seriously, if this girl is asking you for your companionship, for support on her first trip, and then doesn't bother her fanny calling over as arranged, its a bad omen, and you'll be better off alone.
I'm delighted with your dates, though, cos it means I'll finally get the chance to meet you. Happy New Year, Lizzy, and I'll see you around the 23rd or24th. Hope you have an enjoyable and profitable visit.
