Earlier today, in the changing rooms after taking my two year old daughter swimming. Got her dressed and then set about organising myself. Off come the swimming shorts, and in the brief moments it took to find my towel:
Daughter [staring at my twig and berries]: "What's that?"
[Daddy does not respond]
Daughter [serious look on her face, and pointing]: "Daddy, what's that?"
Daddy [fully aware that there are people in the adjoining cubicles]: "Buh... Durr... Mummy will tell you about it in a few years' time."
