I love my stepson - he's great.
He used to be vegetarian but is now vegan. It is a PITA buying stuff for him to eat, so much stuff has lactose and shite in. But, anyway, I cook for him as (a) I am anal about my kitchen and (b) well, he is part of the family. He usually has curries because that is the easiest thing to make. So it's no problem really.
At the weekend he went out and got a bit pickled, came home with a chicken from nandos. He also demolished a load of cheese.
So yesterday I jokingly laughed at him for falling off the wagon. I just said that i assume that I didn't need to go all out and buy vegan stuff any more (soya milk, free from bread etc) as he obviously wasn't that militant about the veganism.
He said no, he still wants to try and be vegan.
AIBU to think this is all a load of old nonsense, it's not as if he got pissed and just slightly fell off the vegan bandwagon and had a bit of cake with egg in it. He had chicken and cheese!
