Obviously you want to be 'totally out' as Jeff put it or you wouldn't be putting Christmas lights on your house. Its a dead give away and just as effective as showing up at the KH smoking a cigarette without the health risks. I also have to agree with Jeff that it feels much better when they know where you stand and you don't have to sneak around. Secretly I think a lot of them will envy the way you broke the chains and escaped and are now doing something normal around the holidays like having fun.
Have wonderful Watchtower free Christmas.
