You Do

Who knows how much I love you,
You do;
No one means more to me than,
You do,
You take December and smile it into May,
And then December comes back again
When you're away;
Who has a charm that very few do,
Who makes life necessary;
You do.
And who can take my dreams,
And make my dreams come true;
Who don't give me three guesses, One will do.
