She tried to hide it, but I saw the look of utter horror on the face of a woman who sat next to me on the plane from New Plymouth to Auckland recently. Her contorted - almost fearful - face was because of my 14-month-old girl, Katie.
Though the sweet little munchkin does get a cheeky glint in her eye when she's up to mischief, and she can scream with the best of them, she's no child terrorist.
What the lemon face lady was scared by was Katie's general state of restlessness as I held her before take off - and how she was flinging the plastic safety instruction card around wildly.
The woman settled into her seat, got out her Woman's Day, and ignored us as best she could. Still, the barbs of tension and annoyance continued to emanate from her.
As parents we've all endured the stares and glares of irate members of the public when your kids are throwing their toys and screaming in confined spaces. Planes are the worst places for this to happen because there is nowhere for anyone to hide.
Before I became a dad I used to have a similar mindset to the woman sitting next to me on this short flight. As a kid howled, or ran up and down the aisle of the plane, I would think to myself: "Can you bloody well keep your kid(s) under control."
