A piece of leather strap is attached to the small knobs of
my dresser drawer so I can easily open the drawer to get some clothes.
Another leather cord is put on the back-door-knob so I can
pull the door closed behind me when I go out.
The knobs on the drawers of my dresser were too small for me to grasp
in order to open a drawer and get some clothing out. Therefore, I had a
piece of leather, or string, or whatever was available at the time,
tied between the knobs of my dresser drawers. I could then grasp this
to open the drawer.
When I go through a door I do so backwards, which means I cannot get
out of the doorway to pull the door closed behind me. My arm just isn't
long enough to maintain a grasp on the doorknob when I'm going through
that doorway! A string, cord, or something similar is tied onto the
doorknob and used to pull the door closed after I clear the passageway.
