I love bookmarks. My favorite bookmark has a picture of my older son, age 1, on one side and a picture of my younger son, age 2, on the other. I’ve used bookmarks for as long as I can remember–but I’m never paid any attention to the way I place it in my book.
My husband places his bookmark in his book with the “front” of the bookmark facing the page he is on. Very clever! Since learning this, I have never been able to do it. If I remember to face the bookmark the right way when I close the book, then I don’t remember to look at it when I next open the book and remove the bookmark. I guess I don’t learn new things as easily as I used to!
About six months ago, my younger son stopped using bookmarks. He was so tired of his bookmarks falling out, that he decided to just memorize page numbers. So far, it seems to be working well for him. I can’t imagine that working for me. My memory is far too weak (see paragraph 2).

The only time I use bookmarks is with interlibrary loan books: I use the reminder slip about the $1/day fine…to remind me to avoid the $1/day fine. Otherwise, I’m a page-flipper: “read this part already, read this already, here’s something new, backtrack, read this already, read this already, here I am.”
