". . . in a blue moon, spill the beans, let the cat out of the bag, chin up, eye to eye, barking up the wrong tree, hit the nail on the head, kick the bucket, under the weather, piece of cake, when pigs fly, and raining cats and dogs . . ."
My family used other sayings too, as many of us do. What I tried to do here was to collect those that I had either not heard outside my family, or at the very most, outside my hometown area (regional). There are always variations of sayings, and you may recognize some but know them a bit differently. I provide meaning where I think meaning is not obvious, or unclear. For those that should be clear, I do not.
