My best friend is lodging with us and has asked me to go with her to midnight mass tomorrow. She's a Catholic but not a practising, she goes to uphold the traditions her family brought her up with.
People have told me IAVU for saying yes and I'm disrespecting myself. My grandparents are Catholic and I went to a Catholic school but because I don't believe in God I should be ashamed of myself.
AIBU to tell them to mind their own business and go and support my friend?
