Pool Crazyness

What would you do if you went to your friend's house for a visit, but when you got there your friend went mental? During the holidays I went to play at my friend's house.  At first everything was cool.  We played some card games and then we started playing pool.  Half way through the game, my friend started acting crazy, he flicked one of the balls into the air and it almost broke the tv.  Then the game came to an end!

I didn't know what to do, but I felt happy because I wanted to see what would happen next.  It was exciting because I thought he would get a big growling.  I was also feeling a bit awkward because I didn't want to get in trouble too.

In this case, what would you have done?  What do you think I did next?
