Keeping cool.

It used to irritate me to no end to see our refrigerator looking like this:

Stacks and stacks of water bottles taking up half the fridge space! My 'common sense' told me it was stupid and pointless, we only need at most a couple bottles at a time. But I kept my mouth shut and let it slide.

Then, a couple of weeks ago, I read an article that refrigerators are actually more energy-efficient when they're full than when they're empty. 

Huh?! (gears creaking) ohh.... right!

Good thing I kept my mouth shut hehe.
