Babbling Day,always October 21, This isn't a day to remain silent. Tell everyone you know about this special day.we celebrate those of us with a glib tongue. You know them when you hear them. They're talking gibberish. They never stop talking. They babble on and on. They can turn a simple one sentence statement into an endless dissertation.Spend this day babbling like a baby, if you must. As for me, I will spend it by a babbling brook.
