An apt excerpt from a poem of the same title by Rani Turton:
Spider on the wall,
You can see us all
Do you wonder as to why
We scurry and worry?
We have our lives to live
(Four score and ten)
Waiting and worrying, often.
This is not the bedtime companion of choice, even high up on the wall, and so I keep a wary eye on where it might be just before I switch off the light!
