Go to Church of the Masses and read the post on priests who insist on being called "Joe" or such. This is another generation gap thing in the Church. Fr. Todd Reitmeyer comments in this post about being given slack for insisting on being called Father. I don't want to call a priest Larry or Bud or Nancy. The post by Barbara Nicolosi is so good I want to quote it all but I will stick with:

"When Mary Magdalen recognized him Easter morning and called him “Rabboni!” he didn’t say, “Hey Mary, chill. Everybody calls me Jesus."

and

"You are a priest, and that dignity supercedes your Joe-ness."
