I have to add my two cents. Just came home from a gathering where the main food was chicken parmagian, pasta. bread and subs. I didn't eat any of it and opted to wait until I got home. It's not that I was being rude- I know for me that if I ate any of that food I would be feeling sick later. It's like ingesting poison. So yeah it's easy because there is such a major difference in how we feel. So, I just socialized , drank my water and then came home and had ribs and an avocado.
