"I'll be done with my breakfast in one Mommy second" J said when I begged her to hurry up for the gazillionth time this morning.
"What is one Mommy second ?" I asked her never having heard that one before.
"It is the time J takes to finish her milk" she told me.
"So what would one J second be ?" I wondered aloud
"The time it takes Mommy to finish her breakfast" she replied promptly.
I also found out that "one Mommy second" is bigger than "one J second" and this is obvious for more reasons than one. According to J, they vary in direct proportion to our ages. Thus Mommy Second/J Second = Mommy's Age/J 's Age.
I guess the point she was trying to make is that my expectation for the time it should take her to finish her breakfast is unrealistic given the Mommy-second to J-second ratio. This was possibly the simplest lesson on gravitational time dilation anyone ever received.
