Earlier this evening.
I asked kiddo to do the dishes from this morning while I started to cut veggies etc. for dinner. Also asked him to clean the stove top.
All of a sudden he gets the plastic spatula out of the drawer, throws open the fridge door and then the freezer door (the little one where you keep icecube trays).
Me: What on earth are you doing?
Kiddo: Well, we are an ecologically thinking household. To clean the stove top I might as well use the ice from the freezer. Needs defrosting anyway. And we save water. Right ?

No argument from me there ;-)
