As something of an introvert, polite company comes best for me in modest doses. Not that I can’t be the life and soul of the party. Just that there’s a finite amount of it I can do. Once my reserves are exhausted, I switch off and get very tired.
Amusing to be interrupted in animated conversation with a friend babysitting for us last night – as we headed off to a worthy house party. The missus pointed out I only have so much sociability, so perhaps best not waste it all before we’ve even got out the door.
Still I could be worse. I read today that the famously cerebral Immanuel Kant’s biographer noted:
The brilliant recluse preferred to walk alone for a very particular reason: ‘he wished to breathe exclusively through his nostrils; which he could not do if he were obliged continually to open his mouth in conversation’.
Kant argue with that.

I laughed out loud. A lot. And then some more.
You just can’t top Immanuel Kant.
And it has to be said that he had a particularly fine hooter.
