Joe was rough and difficult to deal with, yet he had a soft side. Once when out and about with a friend, I'll call him Cloyce just to give him a name, Joe asked Cloyce if he wanted a soda pop. Told yes, they found a store, parked, and went headed towards the door. Clyde remembered a street urchin, a sad and frail little boy sitting over to the side with his knees tucked into his body, trying to stave off the chill in the air.
They went into the store. Clyde went to the refrigerated aisle and grabbed a bottle of pop. Realizing next that Joe was not with him, he found him trolling a stack of bagged oranges. You know how they would bag oranges in those mesh bags, right? Orange mesh bags, I suppose to blend with the oranges. Joe took one, then got a drink for himself, and they went to the checkout and paid. So he wants oranges, Cloyce thought.
When they were outside, Joe went over to the urchin and tossed him the oranges. Cloyce said the boy looked up at Joe in surprise and joy and said, "Mister, when you dies, I hope you goes straight to Heaven." Joe replied ironically, but in a quiet voice, "Aw Hell". It was perhaps the only time and manner in which such words could sound humble.
So Aw Hell can mean a lot of things. You just have to have the right emphasis. Joe was a master of that.
