Two-three weeks ago, Cgfg's mom messaged me and said cgfg wanted to go camping with us this coming weekend. Its not normally her weekend to be here, but mom asked if we could switch so she could go with us, and then she could have cgfg on Easter weekend (found out later her step-kids swapped weekends, and she doesn't like to give up her weekends without kids so works hard to keep cgfg and the steps on the same schedule.) Anyway, we said sure. So cgfg is going camping with us this weekend. Cgfg tells us last night she has a choir concert on Saturday and its for a grade. But mama doesn't want her to stay at her house this weekend. Mama wanted me to stay out of school...I'm staying out of it. I'm sure the concert has been on the calendar longer than 3 weeks. We're going camping, and mom switched weekends on the pretense Cgfg wanted to go with us (and then screamed bloody murder because we asked to swap the next weekend so cgfg can go to a shoot - funny how that works, huh?). Cgfg will miss the concert. I'm making it not my problem.
