As Karen Carpenter Once Said "(They Long To Be) Close To You"

They certainly can.
They certainly do.

They are certainly fine.
They are certainly perfectly content.

But if given the chance, they don't. They'd, simply, rather not.

They, if given the choice, would much rather be together.  As close together as possible.

We have told them since before they could understand all our words, "You are stuck with each other for at least eighteen years.  You can make it wonderful being together.  Or not. It's your choice.  We're just along for the ride." 

I think they have taken us very, very seriously.

When not in school, they are with each other ALL DAY. 
They eat, play, read, work, sleep together...twenty-four seven.

And still, when they go to bed, they talk, for minutes - sometimes hours - before falling asleep.

What in the WORLD is left to say?

It amazes me.

It always has.
It always will.
