Envelopes

My wife is a nut about saving money and recycling. I was just walking around the house, looking for a scrap of paper to write a list on. I told my wife what I needed and she went into our media room and grabbed an empty envelope that she had saved from the incoming mail. She tells me that when she goes through our incoming mail every day, if the back of the envelope is blank she saves it. She uses it later to write notes, make lists, and put coupons or bank deposits into. Sometimes I think she is too frugal, but I know that every penny she saves is a penny I can spend on fun things, so I try to humor her!
