I'm following on neatly from matters concerning what grows on the the head, to what goes on the head. Your choice of headgear speaks volumes, you know. And, that which caresses the cranium may also prove to be an indicator as to what's going on inside. For instance, we have Sherlock Holmes and his deerstalker, and the dear ladies of Ascot and their magnificent millinery. Then there was my maternal grandmother, who sometimes donned a battered sun-hat when sitting in her makeshift conservatory but, more often than not, settled for The Sun to protect herself from...well, the sun.
It would seem that our daughter was influenced by her great grandmother from a very early age. I was tempted to insert a speech bubble for Mags, but I think she was probably lost for words.
