I think the girls had fun at your expense watching what was happening. I'm dying of laughter imagining your face and your desire to kill the squirrel. There are crazy people everywhere, but literally crazy.
In my case, several girls and I had an awkward time at a friend's wedding because a relative got so drunk that he was throwing himself at women he didn't even know. He was completely out of control and doing all sorts of inappropriate things. It was very uncomfortable. Alcohol can do a lot of things to a person.
