A dear friend of mine lost her job last Friday. She wanted to meet up for a drink, but I had booked in a babysitter so I can paint our living room. We haven't done it in years and it was desperate, and literally my only weekend off for 2 months. Friend is now upset with me, even though I offered to meet with her another night instead. I tried explaining that it was the only night we could get a sitter and we had it planned since before Christmas. Wibu?
