Understandable...some say there are two sides to every story, sometimes three! I'm sure a good excuse is coming...I rolled one with it when I got spaced out, the dog ate it, its lost in the mail not my fault or aliens came down slashed my tires and cut my power lines, etc...
Hopefully for his sake he hasn't fallen seriously ill where he can't access the internet, respond to my PMs or mail it out. He may also live in an area where the mail doesn't get delivered or where he can't ship from his house. However, its been since 11/21/12, I think I've been pretty patient.
I know how I am. If have other people's property that needs to be returned or shipped out I do it ASAP. If someone gives me their trust, I do whatever it takes to not let them down.
