There are things I don't like but until I had, three times, an alligator, in the presence of many other observers, turn towards me as I approached and start swimming right to me, I wasn't afraid of alligators. Not that I'd swim with them or anything like that, just that I didn't fear them when I saw one in a lake and I was on shore. Now, since this has happened to me three times, If I know there's a gator somewhere, I don't go there to look at it.
And Buffalo. Just the thought of a buffalo behind a fence and I get verry very nervous. I had to leave the gallery at the auction when a young Buffalo went through. He did try to climb out, I heard, so I'm glad I wasn't near him. But, I'm 5/8 Native American, so, who knows, maybe I was eaten by an alligator and run over and killed by a Buffalo in past lives.
A small child that lived near me was DEATHLY afraid of dogs since birth. He wasn't around any dogs, so he hadn't had any bad experiences in THIS life with them, but he would scream bloody murder if his mom passed my house wheeling him in his stroller and my dog was outside. He was only about 14 or so mths old the first time I saw him and my dog was a little Cocker Spaniel who was just standing there with me wagging her tail.
