Day 21: Why don't I learn?

How many times this has to happen before I learn my lesson? Last time this happened in the end of last year. And if I remembered correctly also then I was away from my rental flat more than just weekend. Now it happened again. I left on Wednesday morning and came back on Tuesday afternoon and yeah - once again door of my refrigerator was not closed. It looked like closed but when getting near the truth was obvious: I had not closed it all the way. And as you can guess - there was lot of ice in the back wall.
