Talking to characters in a way they can relate to and making sure that everyone feels comfortable is a logical thing to do. It may be a strength of an S, but certainly other types could do it as well, especially intuitive types.

I found yet again today that I have a very calming influence on people who are upset. It was kinda funny. We encountered what the real estate industry calls "hostile tennants" today. My boss, who I think is an ENFp, is very good with people, especially upset people. He wasn't able to calm her one bit... it took me about 3 minutes... and I'm not an F! lol
