Day out shopping/cocktails/lunch. It was arranged with a group of women- 2 I'm close to, 2 I know well and the others i know but not well. The two I'm close to cancelled and now one who I know well has cancelled. So it's a group of women who are all close but I only really know 1 of them. She's someone I normally see in a group but don't message/meet without the group. I would lose train fare (£30) but I'll save the food/drink money if I don't go. Should I go?
