I always lock the 2 doors (front and back) at night, and when I leave the house, and it seems pretty important to me. Does safe-guarding my shit fairly meticulously make me materialistic?
Not at all; no need to make yourself feel neurotic about it. I often don’t lock my door when leaving the house during the day but I think I’m in the minority. Wanting to keep your stuff from being stolen does not equate to being overly-materialistic.
