Don, had once been that big brother you see on T.V. Andy had loved his brother.
Then, his brother changed.
At the time Andy didn’t know more than his brother had moved out.
Years passed before he saw Don again. Don didn’t look good, whether he was on drugs or living rough, he wouldn’t answer.
Don wanted to ‘borrow’ money. Andy gave him what he could. A few times he needed a place to sleep, and Andy accommodated..
Although Andy wanted to help his brother, beyond handing him a wad of cash or letting him crash in his apartment, there wasn’t much else he could do.
