My teen, today, out of the blue: "You know, Mom, you are a really good teacher. You do not give yourself enough credit. You said how you could not homeschool me because I was so difficult and could not homeschool my younger sister because of the way she is. You need to stop waiting for others to say that you are doing a good job."
Sometimes, the recognition and acknowledgment will come from most unexpected quarters at most unexpected of times.
