Getting old in the underworld

My main man came to see me. his dog fell asleep in Scouts bed. Scout was not happy with that. I said to him"Your dog is very quiet. That's unusual. Normally it runs about everywhere."
"He's just been to the vets."
"Why? What's wrong with your dog?"
"It ate £10 worth of marijuana. So he's a bit zonked now."
My man was mugged the other day. he was getting £20 out of the machine in the wall, he took the money from the machine, turned around and a man punched him in the face. He fell to the floor and the man grabbed his money and ran off. He was not really hurt but more shocked and surprised. Then he was very angry. He said he knew the man who did it. He knows all the bad people round here.. So now he has all his friends looking for him. This is another world within a world. A world you don't see but it's there all around you. It's the same everywhere.
A few days ago a man we saw an old man, bent with age and arthritis, he couldn't walk very well and was very polite.When he had gone he said "I know that man,When I was growing up his family were the worst. he was the father and all his children were thugs. Everyone was scared of them. They thought they could do anything and get away with it. So they did what they wanted. Can you believe that?""
"No I wouldn't."
"Well it's true. Complete bastards the lot of them. They made everyones lives a misery. Now he is saying please and thank you because he is old and weak."
"What about the kids? What happened to them?"
"Well when he couldn't back them up anymore, they sorta lost their courage. It was false courage. To be fair they were all a bunch of cowards, living on their father reputation and when that went so did theirs. They drifted off to other places. We don't see them anymore. Just him. You wouldn't believe it would you to look at him?"
