"
I&#039 ll have a blue christmas without
you;I&#039 ll be so blue just thinking about
you Decorations of red on a green christmas
tree Wont be the same, dear if;you&#039 re not
Could you imagine having a Christmas without the person you love the most? And when it says "Decorations of red on a green Christmas tree Won't be the same if you're not here with me" It's saying that even when there is festive Holiday decorations, because you miss them so much the memory is painful, even when there are reminders everywhere to be joyful during the holidays.
