How do you wave?

Answer 1

Generally, to wave hello, you keep your hand pointed straight up and wave at your wrist left to right.

Waving goodbye can be with the same gesture, or by waving your hand in a more up-and-down motion at the fingers. The "Queen wave" is a more formal wave that generally twists the orientation of the palm around in a half-circle.

To show more enthusiasm in either your "hello" or "goodbye", raise your arm higher or wave faster.
