So what about the FI...What do they do?

first off, I love Jonathan dearly....but MAN would I love if he was a man in uniform, I have ALWAYS had a HUGE thing for cops - they are so brave and cool - and 2nd firemen! He volunteers in a local fire dept...but it's just not the same!
He is a 'numismatician' which is a fancy word for coin dealer. His dad owns a rare coin business and he works in his office.
