god is santa for adults! i like that concept, seems to work for me lol.
i was raised in, my parents didn't tell me about ol st. nick and when i heard about it at school i thought it was a total crock from the get go! LOL i never would have believed it as a child.
my child was about 4 when we started celebrating. i explained to her that other children are taught from the time they are born that santa brings the presents, etc. but i told her that it is a wonderful story, much like cinderella and such and that the presents you get come from the hard work of the people who love you.
that really stuck with her, and i believe made her much more grateful for the gifts she gets, christmas or otherwise since she knows that people have to work to give and not just some fairies from some whopping endless toys r us drop them off while she's asleep.
now that she's getting older, and her non-jw friends are starting to question their belief in the big SC, she is wise and tactful enough to let them keep their belief if they want to. she doesn't say that she doesn't believe it, she just lets them talk. she actually told me just a little while ago one of her friends asked if she believed in him, she said she never thought about christmas that way, and then let the girl talk. both were satisfied with the convo, and the other girl will figure it out when she's ready.
thing i hate about it is how angry, tense, and nasty people overall get that time of year. they're buying presents they hate for people they barely tolerate when it comes to co-workers and such and i think that christmas should just be a family thing. thankfully, my husband's family is small so we don't have too much to buy.
it is definitely about tradition though, when my MIL brought a box of (all non religious) ornaments from my husband's childhood and explained what each one meant to them as we hung them up the first time...that was magic for me. that is all that christmas is to me; nothing religious (i call it x-mas mostly) but a time to be with the people you love and reconnect.
you might find, in time, that the idea appeals to you if you have friends/relatives who are out. but if all your family are jw's, it can be a very, very lonely time of year.
