Not on the schedule

This begs the question, what is NOT on the schedule?
What have I missed out?
What more could I possibly squeeze into my very tight calendar?

Well the answer to the above questions is.............TIME!!
I trying my very hardest to remember what that is.
Not sure at the moment.

I seem to remember hearing a distant rumour that there is something called 'spare time'.
I'm wondering what exactly that is.
Is there a definition for 'spare time'?
Oh where is my dictionary?
Ahh, as defined by The Oxford Dictionary of Current English, 'Spare Time' is a noun, meaning leisure. What a novel idea!
Further down the page, I came across the word "sparse" meaning thinly dispersed or scattered.
Now that is a bit more appropriate for my version of 'spare time'.
