I don't like the part about using people's names.

I personally don't like it when someone I don't know uses my name unnecessarily. It strikes me as odd and makes me think they're trying some psych 101 tactic on me. It's completely counterproductive because it makes meh mind jump off topic.

It's fine to show that you know someone's name (like at the end of a call), but if you wouldn't throw a friend's name into a sentence, don't inject a stranger's.
