Do not disturb
On my phone there is a button: do not disturb.
So I press it.
Yet immediately my son comes to prod me and inform me of an immediate requirement of ice cream, then bursts into incredulous tears when I explain there is none left, that he himself ate the last morsel the previous evenings when we had resorted to luring him into the bath with said treat. He saw the empty punnet with his own tearful eyes.
I suppose there is a problem with my phone. Either that or my son, but he is more or less perfect.
Perhaps a software update will fix it.
