they...

They are the two greatest gifts I've ever been given.

They are the reason I'll never sleep in again.

They are the best of friends.

They are capable of screaming so loudly and high-pitched that my blood pressure will never be the same.

 They are so different, yet so good together.

They give hugs and kisses to one another.

They can make each other so mad, too.

They can't imagine life without the other.

 I can't imagine life without them, either.

They share no blood and no DNA,

but they are brother and sister.

They are all these things and more.

Thank you, God, they are ours.
