Some of my utility bills come with return envelopes (yes, even in this day of internet banking, lots of bill payments still go through the old-fashioned mail system). At least one of them uses the back of the return envelope to print Child Find alerts, with a photo and information about the missing child. This seems like a good idea, although the most recent example seems to be a bit of a stretch:
First, the information says that the missing child was twenty years old when last seen … have we officially decided that childhood lasts into the twenties? Second, the missing person has been missing for a pretty long time — since 1988 — and it seems unlikely that this photo will have much more than a casual resemblance to her current appearance (assuming that she’s still alive, of course).
