Fit For A Princess

Said the doggie to the Princess:
"I'm a state of some vexation,
And stress and angst and worry
And considerable perplex-ation

"Today it is your birthday
And I've tried without success
To think of something worthy
To give to a Princess"

"I thought I'd give my rubber bone
I thought of that last week
But when I went to fetch it
I found it'd lost its squeak"

"I thought a half-chewed sandwich
Might do the job okay
(I nicked it from a toddler
In the park the other day)"

"Or how about an apple?
Or some leaves or grass or moss?
Some pages from a book I ripped?
(As I recall, you got quite cross)."

The Princess said, "Dear Doggie,
All I need's your waggy tail
Your snuffly nose, your soulful eyes,
Your friendship without fail"

Then doggie said, "That's not right
I give those things for free!
My friendship I give gladly
For you take me out to pee."

"I want to give you something 
Expensive, in a box."
The Princess said, "Well maybe
You could just not eat my socks."

"It's a deal!" The doggie answered
And he proffered Murphy's paw
They shook on it, and thenceforth
It was known as Murphy's Law*

* I give it a week.

p.s. Happy Birthday Princess Normal xx

p.p.s. Ooh, also, no cake this year because I figured you would most likely not be in on Monday. But there's something in the post.
