I hesitate to say that it happens often, but people do sometimes talk about special abilities or super-powers, even if it’s phrased as a “party trick.” Today I realised that I have what might best be described as a special inability.

I took a quick wander into Wimbledon, the nearest town to where I live. It looked gloomy outside and the weather the previous day had been windy and a little chilly. I decided to wear a jumper and my jacket. It didn’t take me long to realise that I had misjudged the weather and that I was very warm.

This happens to me all the time.

It’s a skill that I’ve never had. I often go out only to find that I dramatically underestimated the weather. This time I dressed for arctic conditions but I can’t count the number of times that I’ve misjudged the situation the other way around.

Does this happen to everyone? In town no-one else seemed to have been caught out. Many were dressed in small jackets or jumpers — but not both — a few were in t-shirts.

How do they know?
