One other thing about Christmas that always catches me out is Christmas cards. I never do them early enough. Yesterday I went to the post office to buy some Christmas stamps, but they were out. I was taken aback because I actually felt like I was on the ball this year. Cards written, ready to mail and still only the 21st of December. Not ready early enough according to the Post Office, apparently.
Oh well. The cards went out yesterday with the standard bird stamps.
