When Sen. Barack Obama planted a long wet kiss on the lips of the wife of his running mate during the Democratic National Convention, I was shocked.

I quickly did a Google search and I was relieved to see that I wasn't the only one who was unsettled by the kiss.

When I was a young girl growing up in London, England, etiquette class was a standard part of our school's curriculum. It was sort of like a Finishing school where girls were taught to address boys in the proper manner.

Much giggling and silliness ensued because we were little kids. But at least we knew what was proper and what was expected of us.

I would expect that as adults we should also know what is proper and expected of us in mixed company because not everyone is tolerant of the ways of the new social attitudes.

In my opinion, a man should never kiss another man's wife on the lips in a professional setting unless they're family or swingers.

For Republican presidential candidate John McCain, the rule is simple: Hug your running mate, kiss your wife. It really isn't rocket science.
