Sisters, sisters...

My dearest sister and I, and now she's just another year older...wow, we grow up fast.

Sisters, sisters
There were never such devoted sisters,
Never had to have a chaperone, no sir,
I’m there to keep my eye on her
Caring, sharing
Every little thing that we are wearing
When a certain gentleman arrived from rome
She wore the dress, and I stayed home
All kinds of weather, we stick together
The same in the rain and sun
Two different faces, but in tight places
We think and we act as one
Those who’ve seen us
Know that not a thing could come between us
Many men have tried to split us up, but no one can
Lord help the mister who comes between me and my sister
And lord help the sister, who comes between me and my man
(By Irving Berlin, thanks man!)
