I am sitting in a cafe close to a young family: Mum, Dad, small child - aged approx three years.
Small child wants to go to the toilet. Daddy brings her.
Small child comes galloping back from the toilet, shouting at top of voice "Daddy got stuck in the loo! Daddy got stuck in the loo!"
Daddy lopes back, looking a little embarrassed but also quite pleased that half the cafe is now watching. He's clearly convinced that everyone is thinking "Isn't that little girl so cute? And my goodness, aren't her vocabulary and articulation extraordinary? She's obviously a child genius!"
All first time parents are guilty of this - thinking their own child is amazing in every way. I was guilty of it myself (except, of course, my own firstborn IS genuinely amazing).
Sadly, I can tell by the expression on everyone's faces that they are actually thinking: "Please be quiet - I want to eat my egg salad sandwich in peace and I don't need to know anything about your loo visit, even if it was spectacularly funny."
All is quiet for a moment.
Then Mum goes to toilet. Small child shouts "Mummy will get stuck in the loo too Daddy!"
Daddy replies "Getting stuck in the lavatory doesn't happen to everyone darling, it's not a ubiquitous rite of passage."
Small child (age approx three, remember) looks very confused.
Dad duly ignores confusion, catches my eye and gives me the very smug "see how vastly superior my child's intellect is compared to the average ?" look.
I know it's very bad but I really, really wanted to say "OK, but can she SPELL ubiquitous mate? Now THAT would impress me."
