I rarely eat anything at potlucks. A few things I will eat because I know who made it. The rest I put portions on my plate and say oh this looks good and this smells amazing. I talk and visit so no one notices what I eat or don't eat. My plate looks full but its never eaten. Learned how to eat without eating at potlucks from my grandmother's ladies group at church. I should write a book about that group and what I learned going to all the 'things' they got involved in. I lived with my grandmother and she took me to all her doings. LOL
