Remember to wash behind your ears, in between your toes and under your arms. Keep your nails trimmed and hair clean. Pee without getting any on your feet. Eat when you're hungry, when you're not hungry, play with your food. If you don't see it, ask for it.
Counters are the best place to sit in a kitchen.
Show some discretion. Don't burp in public. Have no qualms about sharing a plate of food, or eating leftovers. Try not to obsess about cholesterol. Be hard to leave.
