Seriously though, there's a time to be corteous and gentlemanly, and a time to be...less so. Let's face it, sometimes it can get boring don't you think? It's more important to be relaxed in whatever you're doing - not too stiff. Allow your personality to breathe and express itself naturally.
Maybe I've just stated a truism...sorry if this is so. In essence, you are absolutely correct...chivalry is dying out.
