As promised, here is a new idiom and we will try to make them more frequent. This is one of my favorites and I recently learned that it does have an equivalent in Spanish, thanks to my father who was visiting me in the U.S. at the time. We happened to be discussing what to do for Christmas Eve and he happened to use this idiom to express what we needed to do.
Care to give a guess?
