Thank you for sharing with us this little piece of history. It is certainly interesting.We were taught to keep elbows off the table also, although I really never understood why.
bobinfaith , I googled this particular manner to see what the history was, you are more right than you may know. Here’s what I found:
Why Did We Start Keeping Elbows off the Table?
Margaret Visser explained to Readers Digest, “For earlier civilizations, it was a way to prevent outbreaks of violence at the table. "Table manners prevented us from leaving our space and starting a fight. It was important that people saw you as considerate or trying hard,"
“In the olden days, crossing that invisible border could be interpreted as disregarding order when social norms were the only thing keeping people in line. People like that were dangerous and capable of anything. "People got scared when you started having bad manners," Visser continued. "They realized the taboo was not functioning, and you didn't know what this person was going to do next."
By the way, I didn't know people in the olden days were such violent beasts, lol.
