2 things:

1) A coworker that seems unable to work around anyone without being almost underfoot all the time, unable to understand how to have an appropriate conversation based on who happens to be around (i.e., he has a tendency to talk, loudly about sex and drugs when either the homeowners or small children are around), unable to shut up (the guy is always talking and/or singing (very badly), and thinks he knows more than he actually does (and doesn't have the landscaping knowledge he should have, especially if he really did run a landscaping crew for a few years like he says he did). Unfortunately, he is also a good friend of the boss'

2) Pissed off at myself for working faster than a probaly should have been trying to finish a project up at work. This led to me half ripping off a finger nail when I accidentally rammed my index finger into a wall block while trying to set a cap block on top.
