ADVENTURES IN SHORT-SIGHTEDNESS #1: That time I went swimming.

In the changing rooms, I hung my white towel on a peg, changed into my costume, and left my glasses in my locker.

I’m extremely short-sighted; I can’t swim in my glasses, obviously, but I can’t see anything without them.

So, I went for a swim—all very pleasant—then back to the changing room for a shower. I grabbed my towel off the peg and started drying with it, instantly realising that something was very wrong. My towel wasn’t the right texture. My towel was, it transpired, actually some lady’s white coat, and she wasn’t very impressed with me.

These days, I wear contact lenses and a pair of goggles while swimming.
