My story about storing things in the oven:
Note: I live with my sister who is a) clueless and b) lazy.
Our oven was very bad. Uneven heating, 2 of 4 hotplates didn't work. We got a new one and while we waited for the tradesman to come and install it, it sat in the corner of the room in it's huge cardboard box.
My sister somehow thinks that doing a (bad job of) the washing up excuses her from all other household chores. So, she was washing the baking dish I used that weekend. This was late Sunday. I was out, got back too late to do anything but shower and fall into bed.
Monday, I trot off to work. While I'm at work, the new oven is installed and the old one taken away.
Later that week, I go looking for my baking dish. My good one, the one I bought out of MY money because I do all the cooking. No sign of it. Go through all the cupboards three times.
Then it hits me. My sister put it on the oven. The OLD oven. The oven that is now gone to the dump. ARRRGH. Then I check again. Not just the good baking dish but the not-so-good baking dish is missing. Sister put BOTH of them in the old oven. I now have NO baking dishes in the house. Double arrrgh!
I still haven't forgiven her but she honestly has no idea. Since then, I've told her not to wash any baking dishes, pots, trays or other cooking stuff. I've had to replace too much of it. (She can wash the plates, mugs and bowls that are heavy enough not to be fragile and the plastic glasses. The rest of it I do my best to get to first.)
