watching eating

Today I sat in Convo and watched a few of my friends eating. I normally sit with them everyday but I never really watched them. Some held the silverware in one hand to cut and switched hands to place the food in their mouths. Some talked with there mouth full and some finshes their food befor speaking. When one was eating chicken with her hands she seemed to eat fast then when she was eating something else with a fork. Everyone eats different and it all depends on how you were raised.
