I was definitely still in Elementary school. I was pondering the circular nature of the days of the week and I realized that time is continuous. I had realized that any time after dinner is still "after dinner"... even the next day.
I skipped dessert one evening and the next evening, argued that it was still "after dinner" for last night. Thus, I should be allowed dessert before tonight's dinner.
My parents are amused now, but oh, the drama that this caused back then was unbelievable. I had a good one. They knew it. And I knew it. But they were parents and couldn't let me win. I get that now. =)
Eventually, I fought hard enough for my Dessert Rights that I was allowed dessert before or after dinner if I wanted to, but on the condition that I finished at least one reasonable helping of dinner. And if I didn't, it would be a whack with the stick end of the Chinese feather duster.
I thought that was fair and I took the bargain =)
