My friends aren't nice about you Mummy!

Driving in the car to go get some lunch today :

J - Mummy, some people in my school say nasty things about you

Me - Oh yeah, what do they say?

J - Well I tell them that you only have 4 senses. That you can't smell

Me - Ah OK...

J - And they say well, if your mummy can't smell then she probably smells herself because she can't smell. They're really mean about you

Me - Haha!! Children always find ways to be mean, lad!

Long pause...

Me - But Jack, you know when you used to wear nappies and I had to change you?

J - Yeah?

Me - Well I couldn't smell your dirty nappies, so not being able to smell does have advantages you know!
