I remember a couple of experiences in the far French countryside...
Once when I was about 13-14 years old I called at a car garage where 3 guys were working on old cars. One closed the door behind me after I got in, and they started yelling and threatening me with their tools. They obviously just wanted to have fun scaring me, I just told them there were other people around and they knew where I was (which was approximately true). When they were tired of it they just let me go.
Another time I had walked a long way to an old house lost in the woods. No gate, no bell, just the path leading there. Before I reached the door two huge dogs come barking. I was not afraid of dogs, but those were really aggressive and they made up a good team. While I was facing one the other attacked on the side and bit my leg. Fortunately the guy who lived there heard them and came up. He told me his dogs had killed a few sheep... (btw he was a nice guy, I started a Bible study with him, but I don't think he ever became a JW -- not sure as I left this congregation shortly afterwards).
