I see what your saying Railgun.
It's unfortunate that Mongo couldn't get his money back but that is not that RARE of an occurance. Anyone who has been in this hobby a while will have some items he got "stuck" with for various reasons.
So what does one do?
You step back take a breather and don't do anything hasty that you might regret later. Don't let your emotions of the moment get the better of you.
Stick the beast in the back of the bottom drawer and move forward.
It is part of this hobby that we will all encounter some day.
