"Oh, I've got another one. Sometime in the early 80s my mom was flying to Germany, with a layover in Reykjavik. On the tarmac in Iceland someone opened the overhead bin above her and a box fell out and hit her in the head with such force that she had to get off the plane and seek medical treatment. When she got back to the airport she found out that the next plane to her destination wasn't until the next day. A nice American couple who happened to be nearby overheard this and offered to let her sleep on the couch where they were staying so she wouldn't have to pay for a hotel, and she took them up on it. Just crashed for a few hours and never got their info.
Now it's roughly 2003, and my mom and I are stuck on the side of a road in Iowa trying to flag down someone for jumper cables. An older couple pull up and jump our car, and we all get to talking. My mom says they look awfully familiar, do they live near us in Des Moines? Ever stopped into her workplace? No, they're just passing through. Then it hits them both: she slept on their couch in Reykjavik 20 years earlier."
#16 I don't see the coincidence here. Guy buys a house and meets a girl... was it 6 houses down from the one he bought? Did he still buy it?
