If planning a house, where does one put the cell? Should it be in the bedroom to keep a close eye on the boy? Could the atmosphere be more appropriate in the basement? What if the basement contains workout equipment and rows of lockers? I feel a bit like the cell should be a place capable of being lived in long term (like a bedroom), but with conditions encouraging a boy to want to earn lots of time out of the cell.
For myself, if I had to select a mood for a cell, I think I would want it in a semi-private area of the house, with adequate lighting for reading (and maybe writing) but with nothing else electronic, just a quiet place to be locked in and have nothing to do but think and relax.
