I woke very early this morning, up by 04.30 and invigorated after breakfast. I embarked on the wall even before coffee. Such is the effect of spring and the escape from a recent head-cold.

There were also some unwelcome colours in the canal.

Probably diesel from a barge.

By 7.30 I had done my good deed for the day. Passing a remote cottage, I spotted bank card in the road. Usually, these things are junk but this one was valid and signed. I did the obvious thing and went to the nearest house and knocked. The woman who answered looked worried at first. Perhaps she thought I was police. I was mostly wearing black. I asked by saying [his name] and she said “yes, he lives here“. His credit card was lying in the road and I reached it over. She must have realised and melted into gratitude. “Are you just out for a walk” you’re not police then?

The card was probably good for a few contactless purchased up to £30 each time before it got blocked. However, it’s worth more to hand it over and make somebody’s day instead. You don’t often get to do that.
