I was having a sleepover at my friend, andreas, house and we were having dinner with her family. I was about to eat when Andrea looked at me with a stern look. I was confused for a second then I realized that they were about to say thanks. Andrea knows i'm atheist, but her family doesn't and I didn't want to be disrespectful so I just went along with it. I just felt really uncomfortable.. I feel like andrea didn't respect my beliefs... should I say something to her?
