What is the worst sound you ever heard?

[glatt]

That sounds pretty bad. I can only imagine.

The neighborhood gang played in the street in front of our house all the time. I was in the backyard when I heard screeching brakes one day. The entire neighborhood ran out to see what happened and watched a poor dog die in the middle of the street. He was yelping and lying on his side with his legs running in the air and a pool of blood forming underneath him.

Then when he was still, his owner picked him up by the collar and carried his limp body behind their house.

I'm sure the driver felt like an ass with 20 people standing there staring at him.

That was pretty bad, but was probably nothing compared to what you heard. I can only imagine.
