DS3 demanded to know why people can drown in water when it has oxygen in it. I explained lungs and gills a bit, but it was hairy, I don't really "get" this stuff yet chem still escapes me, generally. Fast forward to breakfast time. Long conversation about why you can't/shouldn't put out a gas stove fire with water, Canada's eternal flame comes into it, then that weird gas vent with the river on top. Finally, the child appears satisfied... Now immagine a breathless mama thankful for a break in the questions. Wait for it...

DS: "Mama, how do[es] water put out fire if it has oxygen in it?"

Mama: crash. and. burn.

I never even thought about that.

So, I guess I'm bragging that my three year old broke me before breakfast hit the table wink
DS1: Hon, you already finished your homework
DS2: Quit it with the protesting already!
