Taxman is a great Abba. He’s the boo-boo guy; bodily fluids don’t scare him; he makes great French toast. He taught the kids to play War. He reads stories and cuddles and schleps and fetches and all that.

But five years into the parenting gig, he’s still not up on the equation.

You know, the equation.

Time to get out of the house (minutes) = (time it takes adults to be ready * 1.5) + (number of children * number of expected tantrums/2).

For example: 30 * 1.5 + 2 * 6/2 = 45 + 6 = 51 minutes. Work backwards from desired time of departure.

But there are the special circumstances: weather and its accoutrement; meals, projects, or other one-time paraphernalia to bring; and the fearsome x factor.*

So while normally a, say,  7:25 departure time could mean lounging in bed until 6:34, I wouldn’t advise it.

Because there is always an x factor.

Like…spilling a full bowl of cereal all over the floor.

Like…a tussle in the bathroom over who gets to brush teeth first. Which means a) breaking up the fight and b) nobody has brushed their teeth yet.

Like…the disappearance of rain boots. Of course, this also means that it’s raining, and if you couldn’t drag yourself out of bed until 6:45 there is no way on earth you will make the 7:43 train and you will be lucky to make the 8:04.

Just for example. And that was Tuesday.

He’s a really good Abba, like I said. But he’s got to crunch the numbers again on this one.

Not to be confused with the x factor they blab about on American Idol.
