I've been a vegetarian since 10 years old, now 35. My mum/dad have been supportive since the start but the same can not be said for my sister who constantly asks how I'm getting my protein, B12, nutrients etc and has since I've been a teenager.
She did it for the 1,000th time while we were out at a restaurant and instead of explaining for the 1,000th time I just asked her if there is any sort of nutritional/developmental deficiency why am I 6" taller than her, in far better shape than her and a multimillionaire while she regularly relies on our parents for money.
She didn't say anything for a second then raised her voice, asked what was wrong with me and stormed out. DF tried to get her to come back in but was unsuccessful and told me I shouldn't have said that but it was a long time coming.
AIBU to think this was a reasonable way to respond, keeping in mind I have told her over and over again to stop commenting on my diet?
