Fridge

Things one learns when leaving alone and having to leave on a week long, or longer, trip. You must estimate how much food you will leave in the fridge, so as to throw away as less as you can. And you'd better not do it the day before leaving, because it's too late then. It's something to start doing a week before, at least. Of course, if four hungry boys had access to the fridge, they would take care of it, and it would be easy. Being alone, not so much.

I could do it reasonably well in my stays in Columbus and Madrid. It's also always interesting to experiment how well preserved are different kinds of food in the fridge and for how long. It's usually longer than we imagine. Of course, there are always, smelly, failures that set the boundaries of reality.
