Drinking soup or eating noodles - be quiet. Do not reach across the table or in front of someone to get something - that is rude. Ask them to pass it to you. It looks very good, but I'm not quite used to American food yet. Maybe next time, thanks.
Meals are to be slow, pleasant, leisurely times.
Enjoy your food, but talk too. Watch how fast others are eating. Try not to be too slow or too fast - keep up with their pace. Thank you so much. Wait for all to be finished before leaving the table.
