“We’ve all had exchanges where we came up with the perfect reply — ten minutes too late. Write down one of those, but this time, make sure to sign off with your grand slam (unused) zinger.” -The Daily Post
If I have a zinger, I always say it. Even if it’s days later. My policy is nothing should go unsaid. Of course, it should be done with tact and respect. It’s never wise to hurt feelings.
