1 Hour

1 hour waiting between 9am and 6pm,
no return within 1 hour!
What is 1 hour?
Can I only wait 1 hour because 'I am'?
'I am', so eventually 1 hour will pass and I must leave?
Why is it that 'I am?'
Why must 'being' impose limits of time
'I am' says that at one point I will not 'be'.
As soon as I 'start to be'
my 'not being' becomes an inevitability.
Time starts for a 'being' when a 'being' is,
but time has a limit.
My time as 'being'will end,
as did my 1 hour.
