I'm going to have to make an appointment to see my GP. For some reason I'm walking about with a spring in my step. I have a smile seemingly etched onto my face, and I'm generally behaving like Scrooge on Christmas morning, after his ghostly visitations had made an impression on him.
I want to shake people by the hand and doff my cap in the direction of any passing ladies. I want to make 'cooing' noises to babies in their prams, and fuss over people's dogs in the street. I want to fill the world with joy unbound whilst shedding a lone, melancholy tear when singing Louis Armstrong's: 'What a Wonderful World'.
I wonder what my GP will diagnose?
