I remember John. Prayers for his complete recovery, and for justice to prevail.
Two would be robbers did the same thing to my F-I-L in a dark alley behind his business (he was a well driller) one Christmas Eve. One of them hit him in the head with a 2 X 4. When he went down he caught himself on one knee and turned to see who they were. One of them said "He knows who we are now, we've got to kill him", as he rose to his feet. One of them pulled out a big Buck folding knife. Mr. Lewis, as I called him by his first name, simultaneously grabbed the blade of the knife with one big calloused hand and grabbed a handful of the other's hair with his other hand. He snatched both handfuls away from the "essobees", who fled.
Next day when we went to see him at home his eyes looked like he had gone two rounds with Cassius Clay. Mr. Lewis was one tough man, and got completely over the incident. My prayers are that John will as well.
