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. When you’re finished laughing, send this to a Mum.
