I never called him a douche. I know that he owes, and has owed money for a part for 8 months. I know that he has not paid it, and he is clearly stating that he owes said money but will not pay for it because he's upset and acting like a child.

I mean, if he had paid for this part, like he said and is supposed to do, this thread would not even be created, and none of this would have happened. I get that he is your friend, and it is a natural reaction to want to defend them. But, Thomas has no right to not pay the balance owing.
