I haven't known her very long, a few years. She is a work colleague. She is 'vegan' on social media, lots of photos and hash tagging and "cruelty free" style comments.
But a few months ago when we went out for a team lunch she ate pork. I've seen her eat cheese, chocolate etc before.
AIBU to comment something along the lines of ' I love how you see vegan meals as a healthy aspect to your current diet'?? I am starting to find it irritating.
