Imagine the alternatives. There could be catastrophic ramifications.
Microwaving on 50% instead of full power
Sandwich size zip-loc bags vs. snack size
Whip cream on coffee drinks
Having a coffee filter
Putting on marker caps - think small children
Having an extra diaper...AND wipes
Remebering to take your wallet into the grocery store
A few sheets of toilet paper
Can you think of any others?
