Two years ago, the princess realized that on birthdays you become a year older. Until that time, this concept had eluded her; but after her 4th birthday she knew.
On my birthday that year she announced that I was now 30. Being as how that's a bit younger than my actual age, I accepted this new fact of life. Then the next year, I became 31.
All was well until my boys started trying to confuse the situation. How could mom be 31, they'd ask the princess, if the eldest child (aka Thor) was 25? For a while I was able to distract her with shiny things, but I knew that could not last.
"Mom is 31 and Thor is 25?" Her little brain works diligently at this math problem. Her beautiful, trusting eyes look up at me.
"Time was different when I was little." The answer seems to have quieted her for now.
In the mean time, the boys have been threated with dire consequences if they bring up my age again.
