Joan - I am completely with you on the post office!! I make origami and I am having my boyfriend bring the boxes into the post office for me right now. The one time I went in the line was outrageous!
My son is 19 and really I'm not sure what to get him - since we review video games he gets a steady stream of games all year long. He really doesn't want anything. We were even on Amazon last night just looking at books and he's all set with the ones he wants. So it may be a quiet Christmas even for him.
I sent homemade cards with origami out to all my relatives but that's about it. I almost feel like I should feel "guilty" for not getting people gifts, but I don't expect gifts either and really I don't get any

So I am happy without the clutter, and am happy sending origami, and am happy having dinner with people. I need to find a way to release this lingering guilt that I "should" be buying things.
We don't have our tree yet - and Bob even had us buy a fake tree last year because he was tired of pine needles getting everywhere! So we have this tree in the attic. Maybe I'll ask him to get it down today.
