6

In honor of the END (I hope) of this year's birthday season for my first-born son who is now six. I must've blinked, cause where did the time go?

Now We Are Six - A.A. Milne
(beloved author of the well known Winnie-The-Pooh character books)

When I was One,
I had just begun.
When I was Two,
I was nearly new.
When I was Three,
I was hardly me.
When I was Four,
I was not much more.
When I was Five,
I was just alive.
But now I am Six,
I'm as clever as clever,
So I think I'll be six now
for ever and ever.
