i was driving my four-year-old cousin somewhere, and i was talking to her about what time she goes to bed. the conversation went something like this
me:what time do you go to bed?
her: i don't know time. when it's my bedtime, my mommy tells me
me: and you always listen to your mommy?
her: no. i don't like to listen to my mommy
me: but you know, it's a mitzvah to listen to your mommy...
her: (thinks for a minute) then maybe i could do a different mitzvah?
