Public Displays of Antiquity

I've recently realised that I've been starting to display more and more old man traits. It's vaguely concerning.

The first thing I noticed was that when I yawn in public places, rather than doing the normal silent stifle, I've been letting loose with a bit of loud 'Aww, aww, awwww!', even followed occasionally by a 'deary me!' And I don't even realise until after it's done. What's happening to me? As you'd know, this is perfectly suitable behaviour for your own lounge room, in the company of your nearest and dearest. But not in public.

And then this morning, I caught myself whistling 'Rhapsody In Blue', fairly loudly while going up a crowded escalator at the train station. When I realised what I was doing, I didn't even stop, I just went, 'aw, what the heck, I'm just getting to a good bit, I can't stop now.'

I think it's probably a fairly slippery slope from here. At this stage I at least eventually become aware of the action, and recognise its' social inappropriateness. But how long will it be before I don't even become aware, but just do my loud Aww Aww Awww yawns and public whistling as though this was normal behaviour?

And what will come next? The mind boggles. Public ear-cleaning? Public belt-loosening? An appreciation of the smell of moth balls? Shudder.

Yes, the slope is slippery, and I am sliding, dear youngsters.
