That is sad. How’s your grandson doing with his loss? Or, did you mention that your grandson didn’t know him, but you had known him? I apologize for not remembering the details.I mentioned awhile back that my grandson's biological father died of an overdose. Turns out, he had kicked one habit, but maintained another. He had been drinking, somehow his esophagus had ruptured, and he drowned in the bleeding in his sleep. It is truly scary all the different ways we can harm ourselves, and over-drinking is definitely one.
