He wont change.

When you marry a Tiger
You gotta love stripes
Cause it’s his stripes you will see
when you climb into bed very night
No, you won’t ever change ‘em
no matter how hard you try
and your Tiger will have stripes
till the day that he dies

But if you married a Leopard
He will always have spots
So you had just better learn
to love what you’ve got
Cause you won’t ever change ‘em
no matter how hard you try
and your Leopard will stay spotted
Why would you ask why?

If you fantasize a soft kitten
curling up in your lap
the Porcupine you married
Will never do that
But if you try to change him
you surely will cry
So love your little Porcupine
and kiss the fantasy goodbye

Stop always wanting
What he ain’t got
and stop trying to change him
into something he’s not
Just be sure that you love him
the way that he tis
Tiger, Leopard, or Porcupine
He is, what he is.
