Im going with Felix on this one. For example, tonight I had a JV/V game and two of the visiting players are ones that I know very well from soccer. In fact, they both go out of their way to tell me each game that I am their favorite official. And I run into one of the girls other places, (food places, wal-mart, etc.) Everywhere I see her I call her "13" her
VB and soccer number and she always calls me ref. Even though we have a very friendly relationship, it just keeps a distance that I think is healthier. I will give them a high five or talk to them after the game.... but during in the game it's player, number or captain to the players, and ref or sir to me. Just better IMO.
