In no particular order:
There are ants visiting the dogs water bowl inside the house.
Muddy foot prints on the floor.
Laundry hanging outside to dry.
Rubber boots lined up by the door.
Windows opened for a short time each day.
Green things starting to grow again.
Less layers needed to go outside.
More time between refilling the woodstove.
Flowering plants trying to raise their heads.
Dogs digging in the mud.
Moles leaving the excess mud from their tunnels on the lawn.
The birds are singing again.
And did I say Mud?
