Terry PratchettA witch who is bored might do ANYTHING. People said things like 'we had to make our own amusements in those days' as if this signified some kind of moral worth, and perhaps it did, but the last thing you wanted a witch to do was get bored and start making her own amusements, because witches sometimes had famously erratic ideas about what was amusing.
