Aubrey ate a sandwich because they had gotten really hungry and couldn't wait for others to eat.
I need to start eating now. I am so hungry. Go ahead and grab a sandwich while we wait for the others. Are you sure it's okay? Are they not going to think ill of me? Oh that's fine, we're all friends here. No one will think bad of you. Thank you. I'm sorry I forgot to eat lunch today. Oh that's no problem, eat all you want. We have got plenty of food for everyone.
