Things that I have learned by living with a 10 year old boy for 5 days. Penises are magical and must be handled all the time. Noses are magical and must be rummaged around frequently to find trinkets of gold to rub on couches. Peeing in the toilet is for amateurs. What passed for good three minutes ago is now rubbish and should not be tolerated. The mirror is the perfect place to stare at your awesomeness.
