Petty

How is this possible? I was in such a good mood before I come in here, and then I was pissed off after only five minutes. I was even happy for you that you were looking forward to the weekend! And then you go and bitch at me about something stupid that wasn't my fault, and that really isn't a big deal. You ruined my good mood, and I resent you for that.

I hate that you can get to me with such petty remarks.
