Apostrophe S

This is mirrored from my brother’s site. He’s right, some things are just missing this Christmas. But it’s still a good one.

They’re singing ‘Deck the Halls’ /
But it’s not like Christmas at all /
I remember when you were here /
And all the fun we had last year.

I know this is kind of about a guy and a girl, but ’tis how I feel.
