If you don't want your fingers to stink...

After lunch one of my students was intently smelling his fingers. Each time he smelled them, he would wrinkle up his nose. He seemed confused and upset about his fingers.

Teacher: Why are you smelling your fingers?

Student: My fingers stink! [smells fingers]

Teacher: Why do your fingers stink?

Student: I don't know. [smells fingers again]

Teacher: Well, what were you doing outside?

Student: We were looking at deer poo. [continues to smell fingers]

Teacher: I don't think it was deer poo. It might have been dog poo. But your fingers shouldn't stink from just looking at it.

Student: Well, we played with it a little too. [smelling fingers again]

Teacher: Stop smelling your fingers and go wash your hands! Right now! With soap! And if you don't want your fingers to stink, then don't play with poo!
