Had the PiLs to stay for the weekend, and MiL spent most of the weekend complaining about DD1's (who is 13) behaviour and picking at everything she did.
The in laws had arranged to get here about 6ish on Friday night. DD has an after school club on a Friday, she's a member of a team and doesn't like letting them down. The club finishes at 4:30 so she's home by about 4:45pm, in plenty of time for the in laws planned arrival at 6ish. Anyway, they'd decided to leave a couple of hours early to beat the traffic so arrived at 4pm. MiL was not impressed that DD wasn't home when they arrived - both FiL and I pointed out that they were 2 hours early
On and off over the weekend MiL was picking at DD - her hair (too long), her clothes (why doesn't she wear a dress - DD hates dresses, always has, but will wear one if she has to), she shouldn't wear make up, her 'attitude' - DD is 13 and just started her periods a few months ago (she got her period again on Thursday) and is struggling a bit with mood swings and hormones (she wasn't rude or anything, but was a bit quiet and tearful a couple of times). DH and FiL both had words with MiL about it several times over the weekend.
Anyway, yesterday we went out for Sunday lunch. Only down to our local pub for their carvery. It's nothing special, a quiet rural pub, all very casual. DD comes downstairs and MiL starts on at her about clothes - why doesn't she wear a pretty dress, etc. DD was wearing skinny jeans, a smartish top and some black pumps (not terribly different to what I was wearing to be honest). Then as we're walking down to the pub she's on a DD for dawdling and being glued to her phone (she didn't even take her phone out with her). In the pub DD was quite chatty, then went a bit quiet (not sullen, rude quiet or anything, just quiet) and MiL started on about her attitude again and how disrespectful she was, then criticisms about DD's food choices (DD and I are both veggie).
DD went off to the loo and I could see she was a bit tearful so I followed her to make sure she was OK, she said she was fine just felt like she wanted to cry. We had a hug and went back to the table.
So, we get back home and DH and FiL have a quiet word with MiL about the way she she treated DD in the pub and there was a bit of a row about pandering to teenagers and hormones are no excuse for bad behaviour and she insisted that they leave there and then.
Her parting shot was that by pandering to DD and excusing her behaviour as "hormones" we'd end up with a drug addicted tear away.
AIBU to think, that DD didn't do anything wrong, and there was nothing wrong with her behaviour. She wasn't rude at all (she was her normal chatty self, but felt a bit quiet and tearful at times). The way I see it is, she's a teenager, she has mood swings occasionally, it's totally normal and as long as she's not being rude, shouty and sweary (and there's little wonder she went a bit quiet when MiL kept picking at her all the time) there's absolutely nothing I can do about it
