Unfortunately, it does not look like this book has a friend as it has never been checked out, or at least not under our current system. I Have a Friend is by Keiko Narahashi and was published in 1987. It is in very good condition, maybe due to lack of check-outs. :/ The friend in the story is the little boy's shadow, and he describes the happenings of the day with his shadow. One line that I liked was, "He is yesterday's night left behind for the day."
It is a very quick read, with vibrant illustrations. Another one for me to try with my kinders tomorrow to get their opinion.
Almost caught up! Happy Reading/Weeding!
