/cgl/ - Cosplay & EGL

My best friend who is my company to an event lter this year is turning into a radical vegan.
I didn't mind her going vegan back then, though I feared her going extreme (and got a "How could you think this way about me!" response).
But now she won't even sit next to anyone who eats animal products and continues to try and "wake me up" and others too.
I feel like puking. Not just because she will ruin the event for me, she is also my best friend I don't want to lose.
