In the b(l)eak mid winter.

Lost control and rang your bell, I was sore,
"Let me in or else I'll beat down your door."
When two strangers who had been two silhouettes on the shade
Said, to my shock, "You're on the wrong block."

Probably unusual to take a silhouette during the winter months, but I had a go. The hardest part was getting the two birds to look the right way so at least their shape was recognisable and not just two blobs in a tree. Well that is recognisable in the fact that they were at least two birds.
