Riding lessons

I have been riding horses for about 10 years now, and I have fallen off more than I care to count. I don't mind this though, because the more you fall off, the better rider you become. So, I generally don't have a problem with falling off. (Unless it's in the middle of a show of course!) Today is a Tuesday, so I have a riding lesson at 4:00 this afternoon. I have been having some trouble riding one of the horses who is very 'downhill'. This means that Paddington (the horse) has a big rolling canter, and he pulls you forward a lot. Paddington also launches over 1 foot jumps. I should be on Gretal, and I hope all goes well!
