Rule of 3's?

Bad things happen in 3's, correct? I hope so, because my friends and I have had enough. This May, one of my best friends had an electrical fire and her house now needs to be completely gutted. July I found out I had a miscarriage. Just this past week, another best friend's condo place caught on fire and now her condo is basically ruined from water damage. I'm hoping we are done with bad things happening to our group of friends.
