Fingers - their real purpose

Me to 2 yr old daughter: Please take your finger out of your nose.

2 yr old daughter complies.

2 yr old daughter inserts a finger from the other hand into her nose.

Me: Please take that finger out of your nose too.

Daughter complies.

Daughter sticks a 3rd finger into the other nostril.

Me: That finger too.

And on. And on. There are ten fingers, two nostrils. You do the math.
