Some people have a hard time expressing themselves in their environment.
This may be an avoidance of self-expression, but it may also indicate that their means of expression are via their clothes or their creative work, such as cooking or yard work. Bill was someone who clearly used his home environment as his primary means of expression. I suppose I was trying to outdo my friends. It was twelve feet wide by twenty feet long, with a porch five feet wide and a little alcove at the back which was six feet square. It was shingled on the outside, and had a little stove, and doors and windows.
