I've been going through 20 years of Christmas cards. I don't know why I saved them all--sheer laziness maybe. I've thrown away most in the recyclable bin. I've made new cards of some. I've saved almost all photos and letters to peruse later.
It has been a nostalgic activity. Many of the families of students I tutored over the years sent cards with notes saying things like "I'm doing really well in middle school" or "We didn't get a new tutor since we moved. Phillip has read The Boxcar Children and asked for three others in the series for Christmas." But one card, probably from an adult student in the last few years, wrote, "Miss Mary, you learned me alot." Maybe I did--but not enough!
