Responsability
I have been vegetarian for 5 years now, it's safe to say I don't dislike animals. So it was really hard for me to wotness and help during the branding process, both in Prineville and in Carey. But on the second occasion, I got to give the shots to the branded calves; seeing it from up close and actually having to pierce their skin with a needle proved to be interesting. Of course I think there are better way to treat them than to kick them like one of the rancher was doing, but those little thingies are tough. I was afraid I'd hurt them during the vaccination, but their skin is so thick there is just no soft way to do it.
But doing harm is still one of my biggest fear.
