Sounds like you're enjoying your lessons.
I started riding a couple of months before my 50th birthday. I'm 52 now. I enjoyed being on a horse, but felt like something was missing in my riding, so I started taking lessons a few months ago. I still have a ways to go, but I'm trying to absorb as much information as I can. After my lesson is over, if there's more students there for lessons, I stick around and watch them, even offer my assistance when I can. Everyone knows that I'm a beginner and try to make sure I'm understanding everything. Thanks to the wonderful helpful people here, I understand a lot more than they thought I would.
