Past time

or passed time or time passed. Whatever,  it's about 4am, night's candles are not yet burnt out, and yet another night when I wake and sleep eludes me. This time I follow the advice of the sleep experts, get up, have a green tea, and listen to some music. I can't find my radio to be lulled by 'through the night' on Radio 3  or dulled by unwelcome intimations from the World Service. Tick tock tick tock

Go, go, go, said the bird: human kind
Cannot bear very much reality.
Time past and time future
What might have been and what has been
Point to one end, which is always present.
