Ah, drama! I agree with most of the posts: it's mainly teenage girls who are allowed by their parents to become little divas and don't know how to saddle their own horse or how to ride. But there are certainly adult women who act the same way; I always think they need to get a life.
One barn I boarded at was full of drama; large barn with kids and adults always something going on. The stories (they were in business 39 years!) are endless and provided lots of laughs but there was plenty of really crazy stuff that went on too.
My partner says barns are ongoing soap operas; especially since there are quite a few barns where I live and everyone has moved here and there over the years so most people know one anther.
I'm finally at a barn where there's very little drama. I found it boring at first but now I really like it. The joke is now we have to hear what's going on at our barn from someone at another barn. There are still people who carry on the gossip chain for us so its fun some days. The current thread is that our main competitor down the road is selling her barn. Or rather her father is selling it since he bought it for his daughter.
