If you are going to shave your beard, get a haircut at the same time.
I have had a beard for 4 years, but this past friday I shaved it off for a costume party. Since I knew my wife would be distraught over the loss of my beard, and does not like it when I get my hair cut, I figured that doing both at once would minimize the impact.
And I was right! My wife was so upset over my shaving that she did not notice my haircut until the next day. And because the loss of the beard was the bigger tragedy the haircut I got away with it.
For the most part...
