Do things really happen in threes?

Do things really happen in threes or is it just some sort of big coincidence?

This hasnt been the best summer for my family (we'll count today as summer still).     My grandma died less than two months ago, then my uncle found out that his cancer has mestacized (sp?  I dont feel like looking it up right now) and its not stage 4 cancer- not related to his prostate cancer but scaumous cell (?) cancer that he had a few years ago, that doctors thought they had taken out (it was in his nose back then, but theyve found it in his lung and bones).  And the third event?     My aunt go into a bad car accident. She blacked out while driving, had to be cut out of the car, and then airlifted to the hospital.   She broke her back in two difference places.  

All that in the span of 2 months...

I think its safe to say that no one is allowed to get sick or injured for the next ten years or so.  With that being said, I've got my hands full if I'mm going to keep jacob out of trouble!
