I felt the same today. Couldn’t settle to anything, so I put on my old jacket, got my secateurs and spent a couple of hours tidying the narrow footpath near my house. It goes past the houses and an orchard, over a little wooden bridge at the brook, and out into the fields. At this time of year the nettles and brambles, in particular, start attacking passers-by.
I worked my way down one side, then back up the other. Apart from wayward nettles and intrusive briars I also pruned any overhanging new growth on the trees.
By the time I got back home, put the kettle on, and tended to my few scratches and stings I felt happy and satisfied. It’s nice to know that our local ramblers will be able to go for a stroll down the lane without getting attacked by the local wildlife - at least for a few more weeks, anyway.
