Onedismus (on-e-dis’-mus): Reproaching someone for being impious or ungrateful.
I gave you more than half of our peanuts. You just gobble them up. You don’t even look at me. You just keep stuffing them into your mouth.
Can’t you at least say “Thank-you”? I would appreciate it. If you don’t thank me I’m going home to my mother. She would thank me.
