Casper my friendly dog,you'

Casper my friendly dog,

you're white like the ghost.

But little do you know,

you've changed my life the most.

Every single day,

your job stays the same.

Take care of the house,

I bet you think it's lame.

But what you don't see,

what I'm here to say,

is that your job is what gets me through the day.

Knowing that your there,

always by my side,

protecting me always, 

that's why I'm glad to call you mine.
