I ride unicycles for a hobby. It's difficult but really fun. It's a vehicle with one wheel.
I seen a unicycle before. those must be hard to learn!
Yes it wasn't easy. I used to be a street performer when I was younger for extra cash!
Thats awesome, You must be very talented at riding it. 
I think so. One of my most favorite things is riding in festivals and seeing everyone elated by the unicycle.
Uni-cycling is what gets the crowds cheering at most circuses. 
Yes, among all the other things that happen at the circus like trapeze acts, dancers, musicians etc.
That must be fun performing on those for a living, I wonder how much circus uni-cyclist make. 
I'm really not sure. I'd be willing to be it isn't a whole lot though.
I reckon they have to make at least minimum wage but they have special talents and I think that deserved better pay.
