Uh oh, I feel a relapse coming on... I have stopped
payment on my cheque for your therapeutic services.

Don't try too hard. Like many mistakes you make,
it is usually a lack of care. There are differences between
zero, 0, and the letter 'o.'

Which might be why I typed an 'o' in my response,
rather than a zero. My point was merely to ask you
what its special meaning might be for *you*. And
you did not disappoint:

But if you want to play games, the most solid reality
is this: there is, at the base of our reality, the simplest
possible reality, a something versus nothing reality!
And thus a zero, a nothing, is the most important
concept that any person can have and to understand,
and it is this nothing that makes it possible to have
this something, that allows us to have what we have!

I think the 'o' must be a picture of your navel.
