I wanted to add my two cents to this thread!
While I am not religious. I did want to say that I agree with what many others have stated in previous replies.
Christmas for me is about the warmth. Yes the warmth of inside of our homes, on a cold winter day but also the warmth in my heart.
Knowing that when you go down the street, there will be lights, trees and decorations. Knowing that when you come home, there is a beautiful tree and beautiful decorations waiting to be seen.
The lights glisten and sparkle when I view them, shining their spirit into my heart, into my head.
The scent of baking cookies, ready for everyone to eat.
The presents under the tree - with decorative paper, ribbons and love. Love, in a gift that was purchased or made especially for you.
The Christmas specials and movies, viewed each season since I was a child. Charlie Brown Christmas forever remains in my heart.
The magic of the season, the belief in santa claus, reminding us....we were all children once.
The mantel - adorned with beautiful garlands, trinkets and lights.
Sharing this love, these feelings....with people you love, is my Merry Christmas.
