My parents were fairly strict when we were growing up and we would get spanked or punished for doing things they found unacceptable. I was a quick learner, not an angel but I knew the ground rules. Younger brother, not so much. We went to visit our grandparents whom just had their living room and dining room wallpapered, they always kept a nice house. They always had things on hand for the grandkids and we each got a bottle of soda and we're going to sit at the dining room table. Little brother chose a cola, and no one noticed him shaking the bottle. POW! It erupted and sprayed the entire ceiling and some of the walls! My father was ready to kill him. My grandfather, told him to calm down, it would dry and you wouldn't notice it. Well it did dry but you could still see it. Those grandparents were always so forgiving but my dad was livid.
