I was at a friend's wedding a few days ago and was sitting next to a person I had never met before. She was an elderly woman (Norma) who's husband had passed away. As the evening went on, I found she was quite the chatter. Norma had known the bride since she was a little girl. I knew the groom since he was about 8 years old, he's now 33.
At a point in the conversation, we started talking about "up north". My family has an old farm a few hundred miles north of here. I mentioned the general geographic area in relation to a small town and she said, 'Oh, where excactly, I have a friend in that town?'. I told here where, and she said her friend was on the outskirts of the town. Then I told her one of my older brothers also has a cottage in a nearby town on Lake Huron. She was familar with the area and asked if I knew of a certain road, and a "boat house"! I told her yes I did, and in fact my brother's place is fairly close to it.
It turns out she owns this old boat house on the lake of a wooded piece of property that looked abandoned. She & her husband had bought it in the 70's to go fishing. Then she told me she had a cottage about a half mile down the coast & inland a bit. An area I knew fairly well, as I had ridden my brother's ATV by the old boat house & around the dirt roads by her cottage!
On Facebook there's a group called 6 Degrees of Separation, with the idea that we are all only 6 people apart from knowing everyone else. Pretty interesting, since my friend didn't know Nomra had a place up north near my brother or my family's old farm.
