in the air

Seemed like there was something in the air yesterday making people a bit aggro. On my bike I got honked at and a basketbal thrown at me, all with no provocation. At soccer practice we had a pretty good practice, but at the end some of our guys heard a ruckus and went to check it out, three guys had jumped and kicked the crap out of some other dude to the extent that they called 911. Has the weather just been too nice for too long for people? Is the economy bringing us down? Or was it just a moon phase? Or bridge toxins?
