digging companion

I'm digging the far end of the polytunnel starting at the edge that runs alongside 'windfall' path on the outside discovering brambles that have crept in and rooted themselves deeply into the rich, moist soil. I've spotted a robin spotting me. Sure enough, as soon as I'm taking a break he is in and recovering worms that I've unearthed. Now he's perched on the sprinkler pipe, singing.
