I would like to add +1s to so many of the reactions here, but there are too many to quote.

A gentleman knows that being called a gentleman is a positive connotation and not a negative one. He also knows that it takes a lot more than two rules to become a gentleman. A gentleman wears the moniker proudly because he has earned the right by dedication to his positive actions. He is well-spoken and does not encite people to get a rise out of them.

Non-gentlemen like to just ruffle feathers for their own amusement. The mark of a gentleman is quiet strength and not brute force. A gentleman is not pushy, abrasive or rude.

A gentleman, for the most part, would prefer to be called a gentleman rather than a dude. He also knows that he is a gentleman no matter what he is wearing, and at all times and in any place. Some men reach the peak of gentlemanly behavior easily, but others are just lost causes.

A gentleman knows 'the difference," while others remain clueless.

I am expecting return volley! It will be no surprise.
