Year after year my brother and I heard the pranks of other kids soaping windows at Halloween. Year after year my mother said, "don't let me ever hear that you two did that on somone's window."
One year we had the urge to try it. So...we soaped our own windows. The screens, too.
The next morning mom asked, "who did that?" We raised our hands.
Do you know how hard it is to get Ivory soap out of screens? Lesson learned. ;-)
