You promised to pay. Where is the money huh!? You broke the contract from what I am seeing/reading.

Not only that but you said that you bought this truck a month ago and now your pulling something like your losing a home. WTF? Losing a home takes months I believe. So why did you buy this truck? I am assuming and not implying that maybe you were trying to flip it for a profit and not that story that your father had one just like it...
