It's mild, the may flower is bursting out, there are buds on the hazel, the magnolia has flowered, the sparrow chicks are being taught how to forage. Crocus and snowdrop are a memory, and the daffodils are just about finished. It's spring!
The same "force that drives the green fuse" has hit the children: all the local boys are out on the green playing cricket.
It's still March!
