Toilet paper! It was Christmas and some of my students had parents who sent me gifts. Most were small but nice personal things. When I opened the toilet paper, I couldn't believe it. I assumed the parent meant it as a gift for the classroom, but I thought it tacky of them to send it in the guise of being a personal gift to me. I never forgot it, especially considering all of the extra time and effort I had put in to helping their son.
