Alexander Graham Bell famously said, “When one door closes, another opens, but we often look so long and so regretfully upon the closed door that we do not see the one which has opened for us.” We don’t have this problem in our house, because no doors are ever closed. Cupboards, drawers, toothpaste tubes, toilet seats, milk jugs, toy chests and mouths -- all are fated to remain ever gaping.
One parenting article I read said that people who constantly leave doors and drawers open may suffer from attention and memory issues. Not shutting doors could also symbolize a deeper difficulty in bringing closure to more serious situations. "I may be going back to that drawer or cabinet later for something, so I'll leave it open for now," is evidently the subconscious thought.
