Titmouse

So what can you do
There is no lettuce
When no lettuce
Humans are unhappy
We know it
As well as we know
That cancer walks backwards
We know it
And when a swan dive
Sets a nest on a wall
The nests will be next year
We know it
And what can you do
There is no lettuce
A bear sadly grumbles
A titmouse shakes their head
