I get your point, but see, I think if I were to request an apology, I'd in a way give her an audience. It was only her, me and 5 kids there when she said it and I think it's more beneficial when the 3 other childrens parents and myself sit them down (the two other kids were the monster's own) and explain that this is not appropriate behaviour but not make a big stink about it because most of the kids I'm sure don't even think in the direction "xy might be a bad rider / less of a person because she is bigger", an official apology would only direct them there. I'm not a mother myself but I trust that the 2 sets of parents involved (the parents of the 3 other kids) handled the issue very sensitively and the removal of all parents from our activities is a good thing for sure.
I keep wondering what I would have said if there had been no children around... This has fortunately been the first time that I got attacked like this ever and I hadn't even given it a thought before it happened. Would I have told her to stick her opinion where the sun don't shine or just walked away? I don't know.
Did any of you have an encounter like this before and what did you do?
Again, you are demonstrating leadership and common sense here.
Once, I had an argument with a runner in the park. I had had a bad experience when runner with an off lease dog came around a corner suddenly and my horse spun and I blew out my hamstring muscles (no riding 6 weeks). That really made me wary and defensive if I saw runners with off leash dogs , or ones who don't see the horse because they are looking at the ground and wearing head phones, and run smack into a horse, dead on.
So, one day, a woman was running toward me, headphones on lookind at her feet. "Hello!" I shout , several times as she is approaching rapidly. She nearly runs dead into me and when she sees me, she starts and takes out the headphones. "oh, sorry" , she says. But I am now pissed. I scold her. She say's , "I said I was sorry, didn't I?" But, I keep scolding her as I ride away. She follows up with , "I said I was sorry, didn't I? You fat ass!"
I replied, "Oh, that's great. That really is grown up. Whatever . . . "
But, it kind of stung. I hadn't been called a "fat ass" in like . . . . Ever. But, now it's a great laugh for me, and I do have a fat ass.
