Is it an event? Is it decorating? Is it baking? Is the date? Is it the weather? What happens that causes you to start celebrating?
For me it's when the stores start to stock Christmas stuff, especially the bookstores. I go to barnes and noble and find a couple of good christmas reads. Then I watch some christmas movies, browse the stores decorations and start humming and listening to music!
Just today I saw that Target already has their little round christmas sugar cookies (the kind you just put on a cookie sheet and bake with a reindeer or snowman on them).
I picked up Debbie Macomber's Angels at Christmas this morning 9and have already read 6 chapters). I also picked up A Quilter's Holiday by Jennifer Chiaverini. Even though I've been umeployed for the last 4 months I still need my couple of small indulgences for Christmas. It officially starts the season for me...
