What was interesting about not doing the holidays is that on Thanksgiving, we would stay home, but we were allowed to watch the parades on TV. They were (and are) Thanksgiving Day parades, not "Autumn Fest" parades or the similar. But we couldn't go to the town parade on Memorial Day (I mean the real Memorial Day - a veterans holiday for those of you outside the US).
On Independance Day, we were allowed to watch the fireworks on TV, and go watch the neighbors shoot them off (I even brought the police scanner to warn if they were coming to bust the party), and my JW mother even joined me a few years ago at a July 4th picnic/fireworks. But, again, no going to parades in town, or anything like that.
At Chirstmas, we would drive around (especially in the rich neighborhoods) and gawk at the Christmas decorations. But, of course, we couldn't have any of our own.
Do you see a trend here? And, look at my screen-name. We were not an "un-spiritual" family. Makes you think.
