I'm not a parent but my siblings and I have said some funny things when we were young. XD
My brother, one year younger, asked my dad where the sun goes when it goes down. My dad started to explain that it went to the other side of the world. My brother says, "No. I think it goes down to the devil, tells him a few things, and comes back up as the moon."
I asked where Alaska was and my mom said it's waayyy up North. Then I said "Oh, it must be out of our world!"
My youngest brother and my sister wanted to go nextdoor to my uncle's (he works from home). My mom said no because he was working. My sister says, "He's not working. He's playing on the computer!"
I was talking to my cousin on speakerphone and my sister was talking to her too. She asked where my cousin's mom was. "At work", my cousin said. My sister said, "Mom's don't go to work." (Because ours stays at home)
Then my sister, one day, said she was going to poke my mom in the arm because her leg hurt. Probably remembering my aunt doing acupuncture to my dad one time. lol
My mom was trying to explain subtraction with borrowing to my youngest brother. And she tried to explain it easier by saying if he had 2 pieces of candy and 8 people wanted some, what do you do? My sister said "Take some of their candy!"
I don't know if my brother or sister said this, but my dad was talking to me about getting rid of a cow. So one of them says we shouldn't talk about that around them because they have ears and can hear us. My dad says they don't know what we're saying. Brother/sister says "Oh, cuz they moo & we talk? We would have to moo & then they would understand us?"
Then one day my mom was talking to my sister and went off on some subject and my mom ended up telling her that she shouldn't laugh at anyone unless they're laughing. So apparently my youngest brother had done something to her and started laughing, so she laughed too!
