OK, I'm sure in the grand scheme of things this isn't a biggy, but will affect if I say something before next week or not.
DS just started back at local centre swimlessons as finding the club he ' ^really^ ' wanted to join too serious! Friends DC's moved back too.
We put DS and her DC1 into the same group, it was the one DS had just moved into when he left. We decided this was best because they could assess them. I am one for trusting those in the know!
First DS was moved up. This meant DS changing times as they don't do next group up at this time. Friend was not happy and not very subtle with it. ( her DC1 a group ahead of DS in club)
So last lesson DS moved up again. This next group up lessons are at same time as friends children swim/ DS was booked in for in the first place.
Friend rings earlier, just general chit chat and she asks how DS lesson went. Fine I say, then say 'oh, he's going to be swimming at 4.30 again now so we can have a coffee and chat when DC's swim'
her reply 'how does he feel about that?, I was surprised they moved him up and not DC1, I just thought they'd not been watching her properly but I guess they just mis assessed him - not very fair to move him up and then down again though, aren't you annoyed' 
I replied 'hmmmmmmmmm' and changed the subject.
AIBU just to turn up Wednesday or should I tell her first?
(am not sure why but I feel like I've lied somehow - when in fact I just am not interested in entering in some kind of competition)
