I had a bat once , except I thought he was a mouse , and I named him Fred . I was living in a converted attic outside of Cambridge , MA and my roof was slanted . Someone put a wall from the part of the roof that was too low to walk under to the ground , and some of that I used as closet space , and the rest was storage for the person who owned the house .

Generate a question about the above context.
What is the reason you would have to convert an attic for living space ?
