wow, that is super freaky. I would for sure have to stay off the phone for a little bit. Also if I heard a thud and the phone hit the ground, than someone else pick up the line and say it was an emergency, I would call 911. Cause you really don't know wtf just happen....they could have been getting mugged or something, ya never know. But sorry bout what happen, you should go home and relax, toast a beer to the guy too.
Also, to the guy that died while diving off a board...was that in a public swimming pool? Cause for them to have diving boards on a public swimming pool the pool has to be pretty dang deep, so if it was in a public pool I can see some serious legal issues with the city/state over that.
