The Mum Test

Loved this forwarded email:

I was out walking with my 4-year-old daughter. She picked up something
off of the ground and started to put it in her mouth.
I took the item away from her and I asked her not to do that.
'Why?' my daughter asked.
'Because it's been on the ground; you don't know where it's been, it's
dirty, And probably has germs,' I replied.
At this point, my daughter looked at me with total admiration and asked,
'Mum, how do you know all this stuff? You are so smart.'
I was thinking quickly and replied, 'All mums know this stuff. It's on
the Mum Test. You have to know it, or they don't let you be a Mum.'
We walked along in silence for 2 or 3 minutes, but she was evidently
pondering this new information.
'Oh.....I get it!' she beamed, 'So if you don't pass the test you have
to be the dad.'
'Exactly,' I replied with a big smile on my face.
