Things you don't see

So there I was wondering what to blip today.

A bit like the day I wondered why a frisbee gets bigger as it approaches you, and then it hit me.......

Anyway I digress.

I saw a lovely murmuration of starlings and tried to find a place to pull up to blip it. But by the time I'd pulled over they had gone to roost.

So that's one thing you won't see today.

And as I sat at traffic lights I thought about other things we don't see.

For example, red and green, green and amber, and all three traffic lights at the same time.

Have a good weekend.
