Description : As a greeting, why do we say "good evening" during the night, when we ought to be saying "good night"?
Last Answer : We aren't the only ones to do that. The Germans do as well, for example: guten abend and gute nacht. It's just a convention. Besides, one definition of evening is the period from sunset to bedtime ... . Of course, we could all start a movement and try changing the meaning of good night . :o)
