Oh man...that would have caused my Dad to have a conniption fit and then some. Open containers in the fridge is NOT something he takes kindly to. In fact, it may bother him even MORE than finding mostly-full glasses that people poured and didn't drink, or barely-sipped cans of soda.
I think Stephen finally stopped wasting milk by pouring more than he could drink when Dad did his usual rant and then poured the whole thing over Stephen's head. ;-)
Yep, I'm sure that drove the point home very well! LOL!!
