Black Friday Blues

Spent most of Friday the 13th. pruning overgrown trees and shrubs around the hacienda. Finished       (exhausted) at dusk and, after skipping dinner I sat down to the normally relaxing task of posting a cartoon blog post. Whereupon I soon fell asleep and woke an hour or so later with a completely blank mind.
Thus, the accompanying 'toon is a send-up of my own frailty.
