Mina:
Say, you said I should put up a stocking for
presents from Santa, right? I was greedy and put up
one of Dad's big stockings. Me? I'd like... some
shoes, and a cute gold pair of socks. My wish is...
to meet a kind, wonderful man like Dad. To be close
friends with him like Mom and Dad, and to become a couple.

Sotto o-heya ni haitte kitara

english:

I saw Mommy kissing Santa Claus
Underneath the mistletoe last night.
She didn't see me creep
Down the stairs to have a peep;
She thought that I was tucked up
in my bedroom fast asleep.

Then, I saw Mommy tickle Santa Claus
Underneath his beard so snowy white;
Oh, what a laugh it would have been
If Daddy had only seen
Mommy kissing Santa Claus last night.

I saw Mommy kissing Santa Claus

Then, I saw Mommy tickle Santa Claus
Underneath his beard so snowy white;
Oh, what a laugh it would have been
If Daddy had only seen
Mommy kissing Santa Claus last night.
