Behaving is Hard

They provide soda and popcorn at our staff meetings. People were setting their sodas on the ledge that separates the front of the room from the back. 

As I walked by them to get to my seat, I wanted to slap the sodas off the wall right into the laps of the people sitting behind the wall. 

I wasn't annoyed at the individual owners of those sodas. I don't even know them. But, I wanted to knock them off the wall so badly it almost hurt. By the end, I was afraid my arm would just flail out of its own accord, so I held it down with my other arm. 

Thinking about it again now, I still really want to hit those sodas. Sploosh.

What is wrong with me?
