how to scratch your head surreptitiously when you are out and about

I like my head getting scratched. I’d prefer not to do it myself, but finding opportunities for others to scratch my head for me is very very rare. Like it never happens. Ever.

So I could scratch my head like some kind of philistine or I could find an alternative method.

First things, first, find a sidewalk with overhanging trees.

Then locate some nice pine trees with poky needles!

You can see where this is going.

Walk under the pine tree and “forget” to duck your head and enjoy. Oh boy, what a feeling.
It’s especially helpful if you have really short hair and the tree isn’t full of sap.
