Reason 382 for Not Sharing Your Smart Phone with Your Small Children

(Reason 381 being the friend, whose small niece, on deciding that she wanted to help the grown-ups with the washing up, dropped the first grown-up object she could reach on the kitchen ledge into a sink full of hot water and suds.) 

Exhibit A:

A man arguing with a receptionist in an office lobby, his attention divided by a small child pulling on his trouser legs and bouncing about with the energy of a demented flea. 
            Locked in awful battle with the righteous disdain of the Chilean receptionist in magnificent wrong but on her own home turf, the man slipped his smart-phone out of his pocket and proffered it downwards as a distraction for the sprog.
            It worked.  In fact, it worked astonishingly.  Her absorption was total.  However, the touch-pad didn't seem to be as responsive as the little girl wanted it to be.  Her brow furrowed, she regarded it - briefly, and then she stuck out her tongue and gave the whole screen a good washing.  To lube it up.

It being politically unwise to laugh yourself silly at behavior of a small child belonging to a man on the losing end of a front-desk skirmish, I skaddeedled.
