It's not usually one thing, but a combination...
Step one, making the decision, not to go and get my gloves. I always wear gloves when I'm leading horses around the yard, just makes sense to me, I have at least two pairs of leather working gloves, that are usually within reach, either in my pocket or close by. Today not in my pocket, had a quick search around, couldn't see a pair, and thought, "Can't be bothered to go and look, and I can't remember the last time anyone spooked, so it will be OK"
That is how I ended up leading Stewie the Moose and Big Bert up from the field with bare hands.
Step two..another bad decision, I knew that the new shiny grain truck standing in the yard maybe worthy of a second look, and a few side steps as we walked past, but didn't think it would cause an issue, and to be fair it really didn't, they were both doing the ears up bug eyed look as the walked past,.
Step 3, the final straw, and such perfect timing, I could hear a pickup truck coming, and saw the neighbor coming down the driveway, but didn't realize that the farm pick up was coming up behind us....that perfectly choreographed arrival led to Stewie having a major spook, and that is why I now have rope burns, and they hurt.
Moral of this story, don't ever pass on your safety equipment, because that is when the stars align and things happen. I was lucky, I have a sore palm, but it will heal quickly and without permanent damage, some choices we make can lead to worse consequences.
