NICKNAMES

How do you guys feel about nicknames? I've chose the name Deacon James and I love the nickname DJ but that's it. I really hate the nicknames Deacs, Deac, Deacdeac, etc. and I don't understand why I'm choosing a name for my son if no one can respect that I chose the name and have asked them to use his name or if they must use a nickname to please use DJ. I need some help! Am I over reacting? Pregnancy hormones or do you ladies agree?
