Odd coincidence

We recently bought a condo. Just out of curiosity, I wanted to find out more about the previous owner. I know he died so I wondered if there was anything online like an obituary. Well, I looked him up and there was a whole site dedicated to him. He was 85 when he died but what struck me was the day he died was January 11th. This date is special to me because that is my mom's birthday and anyone reading this probably knows that my mom died in 2008. I just found it really odd that the man whose condo we bought at a great price died on my mother's birthday. No cause and effect, no twilight zone, just odd.
