Once In A While Someone Crosses Your Path Who Doesn't Trip You
I came up with this quip today at the grocery store when a lady told me that I actually helped make her shopping experience pleasant today!
I quickly replied "Once in a while someone crosses your path who doesn't trip you." without even thinking - then the grocer looked up and laughed and said that was one of the most witty replies he'd ever heard. I did not realize how witty I could be when trying to effect a bit of self effacing humor!
