There are many aspects of Christmas that I don't like, the commercialisation, the lying to children about an invisible person who brings them presents, the over indulgence and so on. On top of that I don't have any cultural background of Christmas traditions, so the tree and the turkey and crackers and tinsel have no resonance for me.
BUT! The glow of the lights in a dark time of the year, the spending time with my (non JW) relatives and seeing their joy at giving our child gifts... is magical. who in their right mind wouldn't want that in their lives??
