A childhood belief about general

When I was younger we lived out in the country and had an abundance of salamanders and frogs. One day I saw a striped frog and had just learned that there was a such thing as poison dart frogs, which looked similar to this particular frog in my yard. I ran in to my mother, screaming that we had a poison dart frog in the yard and that it would kill us all. She told me it was, in fact, a poison dart frog and that I should kill it, just joking around with me and knowing my love of animals (and assuming I wouldn't do it). As much as I hated this idea, I was afraid it would kill my family, so I ran out and stepped on it, twisting around on it to really squish it. Some of the blood gushed up onto the open toe of my clear jelly shoes and I freaked out, believing I was going to die because the blood was on my shoe and could get on my skin. I went inside to tell my mom that I had killed the frog and that I was probably going to die because of saving them. She was flabbergasted that I had done such a thing, but also could barely contain her laughter. She never told me it wasn't a poison dart frog until I was much older, so I thought for the longest time that we had them in our yard...but I never killed another one.
