I got this at work during one of the feeding sessions they were giving us. Seriously my work supplies us with pizza, cake, or tacos atleast once a month minimum. But I made myself 2 tacos. And figured out half way through I had too much and would not be finishing.  Coworker turns to me and comments on how I'm not finishing my plate. I Just tell him that you don't have to eat everything on your plate, nothing and noone is forcing you.
