Being a gentleman isn't always easy in today's society. You are often mocked or scorned. People put lots of road blocks in your path to prevent you from being a gentleman. Some will call you out-dated or just not up to date with how things are in today's society.
It used to be acceptable to open a girl's door for her. Now it's often ridiculed. This begs the question of whether it's okay to be a gentleman or whether it's best just to ignore the issue all together.
It makes people ask if opening doors is chivalrous or just a waste of time.
