Extremely long day ahead for me and I have this sinking feeling that the people we've assigned to work on stuff for the satellite project haven't actually done any work.

Sometimes, it sucks being right.
New Rant:
Had an extremely tough go of my homework yesterday. I was supposed to work on it with 2 guys, we'll call them Bob and John. Now Bob had already finished his homework, but John and I were stuck on one problem so he offered to show us where we had gone wrong. We planned to meet up at 9:00am but Bob forgot his work and told us he'd go home, grab a bite to eat and meet us after that as he had to come back on campus anyways.
So John and I go to work. 3 hours pass and we're stuck on the same problem. We know there has to be something trivial holding us up but we can't find it. So we go looking for Bob and sure enough, he's sitting elsewhere on campus working on other homework. He didn't have the decency to just drop by and hand us his homework so we could look it over like he said he would. We weren't asking for any more of his time than the 45 seconds it would take him to drop off his work.
So we run into him and he give us his homework and we look it over and sure enough, a single missed variable had held us up for 3 hours. Then I compare my other answers to Bob's and I notice a slight error in his calculation. The homework said Do A and he Did B. No big deal, I go over to him and show him the error. Nothing major, no big deal, stuff happens like this all the time.
He acts completely incredulous and denies the problem. Now I'm not angry at this point, because it hadn't sunk in yet what a douche he had been by leaving us hanging for 3 hours. So I'm not angry or emotional, I'm just calmly showing him this trivial error. He then goes, "Well I didn't do that" with attitude dialed up to 11.
He takes any error he makes that is presented to him personal and denies it's even an error. Like a five ear old denying they had been in the cookie jar, he claims to have not made the mistake. It's staring him in his <disparaging language redacted> and he's denying it even exists. With extreme attitude toward me. I just walked away, it was either that or <violent threats redacted>.
Then later he comes over and asks me to walk him through the mistake again and I do and he's coming up with every reason to show it
really wasn't his fault, it was the professors fault obviously.

Whatever dude, don't care. Then he asks me if I spotted anything else and I told him I had found another mistake in his work and proceed to show it to him. While this mistake was a bit more complicated than the previous one, it was still relatively straightforward to prove he was in error.
Only he immediately starts arguing with me before I can finish explaining the mistake. I just walked away from him at that point, I'm not going to beat through his ego to help him correct his homework, he can take the goddamn point hit on it.
This is the same asshat that argues over everything in the sat team project and I have him in all of my classes and will have him in all of my classes for the next two years. Where's the suicide smiley?
