Because I celebrated Christmas and all holidays till I was 20 and became a JW I loved the seasons and hated giving them up. When I had children I would take my boys out on rides to look at the Christmas lights, and we all drooled with envy. Their JW Dad didn't know I did that. LOL I missed it all the years I didn't celebrate.
I know lots of witness that did the same thing I did, because they loved the lights in the winter time. Their beautiful how could you not love the appearance of it. My ex though used to say look at that house that was all decorated and say how disgusting that is. The boys and I would smile our little secret smiles.
