Another area I know that has embarrassed so many young men is the issue of shaking hands. know that men shake hands when they are introduced to each other but it is left for a girl to decide whether to shake hands with a man if he is introduced to her.
As a matter of courtesy, don't offer your hand to a girl for a handshake unless she invites that. It has embarrassed many young men.
Thank you and God bless you.
