30+ Behaviors That Are Only Acceptable in the U.S. According to Non-Americans

I have so many questions about this next one. Why is it rude to stretch at the dinner table? Is this referring to that sort of big stretch where you lean way back in your chair and stretch your arms overhead and groan? Or to any stretching whatsoever? Because little stretches don’t seem so bad.

But on the other hand, how odd for this person to declare that they adore stretching at the dinner table. Is this something that people do? Is this a normal part of the meal for many Americans? Should I start stretching at the dinner table and see what I’ve been missing?
