Good day or bad day?

I am fucking pissed. My mechanic keeps fucking stalling, he was supposed to have my truck fixed (got a new motor for it) a couple weeks ago, well now he is saying he didn't think that motor was working so well (yeah, whatever chief) so he is waiting for a new motor to come in, which wont be here until friday or saturday. So that means he wont start until monday or tuesday, give him until the middle of the following week... I have to kill someone, okay?
