Good manners says it's not right to put your elbows on the table......... . However I have scoliosis.....curvature of the spine all my life, and I don't like to tell anyone....and it helps my balance when I PUT MY ELBOWS ON THE TABLE..... . and you definitely need to tell the other person that it is rude, and downright illegal to put you hands on another's elbows or any part of any other person's body, without their permission.. . Yes, your so called friend was rude, and broke the law by assaulting the other child!. . Now, remember that for the rest of your life...asssssault....is just not right...no matter how uppity the other person thinks they are.. . It takes a real friend to say, hey, don't hurt my friend and don't push people around!!!!!...it affected you so badly, that you wrote it down...here!
