1. I was waiting in line at hardware store in Houston when a long plank someone had leaned against the counter slid down and bonked me on the head. I had to sit down for a minute, stunned. After a few minutes, the cashier said he had taken the name and address off the check of the customer whose plank it was (in case i wanted to pursue it, although it should be store responsible, not the customer). I did not want to, but I took a glance at it-- the address was an apartment building I had previously lived at, including the same apartment number.
2. I met a girl in a bar and we were chatting. We found out that we had both lived in a 4-apt. building called the Red Barn (shaped and painted like a barn) and in the same exact apartment.
3. I rented a place in Birmingham that later I found out from my mother that my parents' close friends had lived in when we were little children and I had played in that apartment.
4. When I was 12, my tennis teacher married my piano teacher and moved into my old house (which had previously been sold to someone else).
