It doesn't matter how delicious the meal is, how much everyone loved it, how much everyone is looking forward to leftovers the next day; if I don't remember to pack it all in those handy little Glad/ZipLoc tubs myself, I'll get up the next morning to find last night's meal moldering in the pots and pans.
Last night, we ordered pizza from a new place. It was not a hit: it was too greasy, too salty, and over all, just kinda nasty. Everyone agreed; nobody expressed any approval whatsoever.
As I was heading to bed, I noticed that the pizza was still out on the table, and decided -- screw it. I don't WANT that stuff in my body again. I'm just gonna leave it out, and in the morning, I'll dump it because it was, in fact, left out all night.
This morning, I got up, got a glass of juice, and found a neat, tidy stack of ZipLoc bags full of pizza in the fridge.
My family can't even SLACK dependably.
