This probably sounds silly, innit? You can make light of this issue, but it really isn't. I know many cultures would allow several things as appropriate, let's talk about the African culture. Personally I think anyone can, but there's this ego thing in a man that would drive his demand for it. I listened to a heated debate about who greets the other first in the morning or at any other time of meeting and a man was so tough on the matter. He said his wife will never sleep in his room another night if she doesn't greet him in the morning. How crude I thought he sounded. Does it really matter who greets who in the morning in a husband-wife arrangement?
