Then you are a better person than I. If someone speaks too familiarly, acts too familiarly, or dresses too familiarly in a serious or business setting, I will not be thinking that he respects me enough to think that I am a person who can find more useful signals of respect than the ability to memorise and abide by arbitrary rules laid out of the unseen gods of grammar, social conventions, or menswear. I will be thinking that he has no respect.
