I'll never forget this - when I was in first grade (64 years ago!), all our bedrooms were on the second floor. I was downstairs in the kitchen with mom getting ready for breakfast before going to school. Well, daddy was getting ready for work upstairs. My baby sister was sleeping upstairs. Mom told me to go tell daddy breakfast was ready so I went to the bottom of the stairs and hollered, "Daddy, breakfast is ready". Mom said, "Can't you yell any louder?" So---I REALLY screamed, "Daddy, breakfast is ready". Mom came running in and slapped me a good one. Took me a LONG time to figure out what I did wrong!
