Now we are Sixty

Thanks to my workmate Isabell for decoration of my desk before I got to work yesterday. Thanks also to those who responded to my lunchtime meeting invite, pace A.A. Milne....
"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 sixty and tired and grey,
Please join me for drinks on my special birthday".
