When I was a kid, the boys’ bedroom had wood paneling which was lighter in one spot than the rest. One day I asked about it.
It was where one of my brothers puked on the wall one night when the whole family got sick at the same time. Dad had been doing all the cooking because Mom was in the hospital, waiting to give birth to me. This particular night, Dad’s dinner included a side of peas & cheese - peas and cubed cheddar mixed with mayo. The mayo must have gone bad.
1 Dad + 9 sick kids ÷ 4 bathrooms = one hell of a mess.
