This I am not joking about, just so you know.
While having my car inspected this morning, the woman behind the counter told me about what happened to her neighbor kid a couple of days or so ago. Since I don't watch the news, I didn't hear it.
Her neighbor's kid, age 4, was playing hide n seek, and the the top was off the septic tank and the boy climbed down in it. Along came the other neighbor and saw the top was off and put the top on and sat a brick on top of it.
The boy was found dead in there, due to gases. He was found by a heat sensor plane above.
Her son went to the school with the father of the deceased child. We stood there and cried.
