Baby it's cold outside...

Back in 1983 I was an engineering student and I had a classmate who wore sandals, except in Thermodynamics Labs (what we would now call PPE rules). One day Brisbane had a rare near freezing morning, and a bunch of us stood around outside our first class speculating on how he'd respond.

Yes, despite the frost, still in sandals.

Toe Socks. Rainbow coloured knitted knee length toe socks held aloft with bicycle clips...

Real Life is way weirder than fiction.
