To be livid DD was made to throw her homemade cake in the bin

[justkeeponsmiling]

Last Friday DD1 made a Victoria sponge during her cookery class in school.
About 15 mins after coming home from school DD was picked up by xh's mother to spend the weekend with her paternal grandparents. Xmil turned vegan a few years ago, as did xh and his gf. Xpil is still eating meat.
DD wanted to take half her cake with her, as she hadn't had a chance to try it and thought ger grandfather would like to try it, so I put half in a box for her to take.
Tonight, DD told me she hadn't tried her cake, her grandfather had a piece and said it was lovely but she "hadn't been allowed to try it" as it wasn't vegan, so the rest went in the bin...
WTAF?
Fuckers!

That's seriously mean. And weird. Bless her.

No I haven't spoken to them about it, only because my DD hates confrontations of this kind and I know it would get rubbed in her face in one way or another by both xh and xmil, a la "your mother has been complaining to us" etc etc. I know this from many previous experiences when DD has been told I'm wrong about things, I'm a liar, etc. about various disagreements in the past. It used to upset her greatly and DH and I decided some time ago that it wasn't worth it.
When xh family does something that pisses us off we disagree with (as for example in this case) we try and stick with saying something like "oh that's a shame" or "well I don't know why they did that" and leave it at that then bitch about it when DD is out of earshot It's less upsetting for DD I think and I'm hoping that one day when she is older and maybe has children of her own she will look back at their behaviour and realise that a lot of the time they were total dicks.

Btw, I have no problem with her eating vegan food when there and them not wanting to buy or cook non vegan things for her (each to their own!) but forbidding her to eat something vegan that happens to be in the house I think is wrong. And making her destroy her own backing is just fucking cruel!

I think you just need to let her make another at home and all enjoy it together.
