And even if you aren't nervous there's the risk that her horse will injure yours. A while ago I went out with a lovely lady but her horse was a nightmare. She insisted he had to go in front, but then he kept spinning & running back to or past us & she made no attempt to prevent this behaviour, In the end, even though I was several horse lengths back, hers crashed into mine sending him onto his knees. Luckily he wasn't hurt, but he could have been & I was very annoyed with her since she still couldn't or wouldn't do anything about it. I told her to get & keep behind before my horse was hurt by hers and, much as I like her I haven't hacked with her since.
