What is the most tragic thing you've ever had to deal with

[Big TR]

Not me but my cousin.

He's a lawyer, working to put his wife through med school. 2 weeks after she graduates from school, she files for divorce. He's obviously torn apart.

A few years go by and he finds somebody new. They get married. Less than 1 month after they get married she gets into a terrible car wreck and dies.

He just keeps plodding through his days, knowing that if he was able to find somebody after the first debacle, he will find somebody after the second tragic debacle.
