Lunch with the 4-year-olds

I had to come in early for work today because 3 teachers are out with strep throat. (I know, lovely, right?) Anyway, I ended up helping out with lunch in the preschool room and had a very interesting conversation with a 4-year-old boy at my table. He began by excitedly talking about blood and how he's learning all about it in a book. (Which by the way is not something 4-year-olds usually talk about to any great depth.) I let him talk for awhile, but after about a minute of extensive blood talk, I noticed that the other kids at the table were starting to look a bit nauseated as they were dunking their corn dogs in ketchup. So I sweetly asked him if we could talk about something else...

"Okay, Katy....But did you know that your heart is what pumps all the blood in your body? All that blood!! Even up to your head!"
"Alex..."

pause

"And did you know that your blood flows through lots of tiny little tubes and-"
"Alex!"

pause

"Their called veins and!-"
"Alex! I'm serious! We're eating right now, so we're not going to talk about blood anymore...Okay?"
"...Okay."

pause

"Butwhenyouscrapeyourkneesometimes...the blood will leak out. Just leak right out....Just leaking...blood...Did you know that...Teacher Katy?"

He just couldn't control himself. It was quiet humorous.
