People at hockey games who tell you how to sit in your own seat. For example, two of us went to the hockey game and the guy behind my friend told him to sit down lower in his chair because he felt his head was too big to see around it. Now c'mon, seriously, can that really be? Also the people next to you in the center rows that tell you to sit back when you are barely leaning forward to see the other end of the rink during the action.
Drivers who move to the other lane with less traffic only to try and squeeze back in when they need to turn onto the ramp on interstate.
The pop distributor in grocery stores that turns the 12 pk box upside down from the handle! (that would be my sisters actually!)
Last but not least....stupid people piss me off!
I feel so much better now!
