Maybe you hit a bad mailbox?

As far as we know, pretty much everything we sent this year has made it. I was not particularly careful in addressing them either.

However post mail was very slow. I had a package that should have been in by December 15th that arrived on the 23rd. (At least it was in for Christmas!) The Holidays are a terribly busy season, and packages are a priority compared to letter mail I think...

I hope all of your wishes make it before the New Year.
