A song has been stuck in my head...and this seemed to fit:

"Those schoolgirl days of telling tales and biting nails are gone
But in my mind I know they will still live on and on
But how do you thank someone who has taken you from crayons to perfume?
It isn't easy, but I'll try....

If you wanted the sky
I would write across the sky in letters
That would soar a thousand feet high
`To Sir, With Love'

The time has come for closing books and long last looks must end
And as I leave I know that I am leaving my best friend
A friend who taught me right from wrong and weak from strong
That's a lot to learn, but what can I give you in return?

If you wanted the moon
I would try to make a start
But I would rather you let me give my heart..."
`To Sir, With Love'

"Lulu" (Thanks Dan!)
