Magnets

I'm for the Cowboys, he's for the Redskins
He calls them Cowgirls, I call them Has-beens.
Hi I'm a Mac and he's a PC
And when he has computer problems he comes and sees me.
I prefer cats and he prefers dogs
Somehow our flea circus happily gets along.
I listen to jazz, he listens to indie
I think that's his way of being a wanna be hippie.
I sleep on the right and he on the left
I guess that one worked out for the best.
I take physics he take biology
When we get together it becomes chemistry.
He sings in the shower, I sing in the rain
Obviously the things we like aren't the same.
How do we keep this relationship in tact?
We're like magnets, opposites attracts.
