Alrighty. Monday I moved my garbage can back to its proper place. Tuesday morning it was where I left it...almost. It was sticking out about six inches further than it should have been. Considering it was 12 feet away the day before I consider this a small victory.
Personally, I think it would be interesting to have everyone in the office who has been affected by this to do the same experiment. Then we'd all move our trash cans back at the same time.
