First off, we are a strictly vegan household for moral reasons. I invited my sister for Christmas lunch as she is recently divorced and has nowhere else to go. I usually put on a magnificent spread with roast vegetables, tagine, stuffed peppers, vine leaves, falafel, home made hummus etc. My sister has just sent me a message saying she's going to bring her own chicken to cook. AIBU to say no way! I don't want chicken cooking in my nice clean vegan oven! Plus the smell makes me feel ill 🤢 I don't want to upset her as she's very sensitive at the moment but surely she can do without chicken for 1 day.
