Once a year, I was able to pick what I wanted to eat for dinner.
My family had a strict rule of only eating food together, at the table. I remember getting grounded (several times) for sneaking Pringles after school.
This led me to figuring out exactly what i really liked. Surprisingly it never occurred to me to stuff myself on everything.
As an adult, I keep food in my fridge that everyone likes (especially the kids) when they come over, even stuff I don't touch. I also keep several flavors of Pringles stored in the pantry.
