Ever have a bad day affect your officiating?

[Huntin' Ref]

First off, to give you a little background of my style.......I generally talk to and joke with the players on the floor. My talking and lightheartedness are know where near a level of a distraction, but enough to engage them and show them we are human as well.

Ok, so here we go....I was working a boys V game Friday night and received an unusual question from a coach (whom I've never officiated for) on a dead ball.

Coach: "Are you mad at me? I feel like you are mad at me."
Me: "No, I'm not mad at you" ~ then we played on.

At halftime I walked over and talked to the coach and asked him why he asked me this question. He said that everytime he tried to ask me something or make a comment I would turn and glare at him in a robotic nature. After thinking about it, I realized that I really wasn't in the best mood the first half and was acting different than I usually do. So my question is, do you ever have a distracted half/game because of your life/job/etc?
