This may seem small but yesterday we received a letter at work from the IRS telling us they had changed our mailing address. It listed our old address and said it would be changed to the new one. The next letter we opened was also from the IRS and it had our new address on it. The letter was sent to confirm that they would now start using that address. Two nearly identical letters sent in two different envelopes. Why not just list the old and new address in one letter. I hate inefficiency. What sucks is the only change is our street is now called a Road and not an Avenue.
