Well, my grandson was right! Deer eat people.
When he was three, he wanted a tent set up in the yard, so I took care of that task. My stepdaughter lived in a home on my ranch, and both my home and her's are enclosed in a fence. After a day or so he said he would like to spend a night in the tent, so I prepped the bedding. As it was getting dark, he started to watch the deer walking around outside the fence, and it was bothering him, and he told me so, he thought they were going to eat him. I told him "deer don't eat people" and he responded, "I'm not people, I'm Noah, and they are going to eat me!" With that, we went inside and slept!
