Attitude? Is attitude asking where the hell my things are one week after you received the money? If so then yes, guilty as charged.
I never asked for you to send before. It has now been seven days since you received the money and, by your own admission, the engine still has not been sent. So go ahead, use all the choice words you want. That will not alter the basic facts.
You have been hanging around your pupils playground too much mate.
Oh please! What are you doing that is helping out eh? You wanted to sell something. I agreed a price. Where does the martyrdom now come into it?
