Plastic containers

Ah!  You made the greatest meal for supper and there are leftovers.  Yes, like me you put them in those plastic containers that we have in the cupboards.  Then we stack them in the frig hoping that someone eats them.  Of course the ones we save for ourselves are the ones they sneak eat.  Stacy does take some of the leftovers with her but forgets to return them in a timely fashion.  Of course in the winter I don't mind, but in the summer, in the heat!  She brings the containers in all at once, drops them and runs.  Yes, they are gross and of course smelly.  I get to open them and get the stench!  I have asked why she can't just return them on the same day, "I forget" is always the answer I get.  Maybe I should forget to make meals.  What would she do then?....
