Table manners

Since returning, I have realized in 3 different times that my table manners have disappeared. I am not surprised. When an entire sub-continent eats with their hands, I guess what we would consider table manners are not a part of the dining culture. And when you are exposed to that for the better part of a month I am sure it is bound to wear off. For example, whenever we would have a meal in Bangladesh, it would be like everyone was pulling up to the trough. People would eat fast, with their elbows on the table, would dish up their food and not pass it along, would make sucking noises while eating and would indulge their entire hand into their plate of food, the lick it off when finished (sometimes up to the forearm!). At the conclusion of their meal (at which time I would be done about 1/2 my food), they would proceed to get up from the table, walk over to the communal sink which was usually in the dining room and hoark. This wasn't a quiet spit either. More like multiple digging from their throats with massive amounts of air derived from the diaphragm. So if I happen to eat with my elbows on the table and speak with food in my mouth for the next few weeks while I am adjusting to a mannered society, please forgive me.
