1) Setting up a Christmas tree is just annoying as hell. If I *don't* set one up, I feel guilty and unsociable. If I *do* set one up it hangs out too long after the fact and I feel guilty for not putting it away sooner. My record for taking down tree late? Mid-March, 2004.
2) I'm sure Jesus loves that this is what I'm focusing on at Christmastime.
3) On the other hand, there's a lot of debate among biblical scholars about when Jesus was actually born. Some push for as late as April. Technically, Jesus might be totally thrilled with me for having that tree up in the spring.
