Yes, where I was raised, belching after you ate, was a way of conveying to the host that you enjoyed her cooking. Then I came to the states and everyone thinks, I'm rude. How ungrateful!
Yep, I'm not ashamed. I know what I'm saying. "Gosh, Darn Great Food!"
we eat less for no belching.
None that I know of they run for cover and do it:-)
