Some say girls like mirrors. It’s nice to be able to look into a mirror and see if you have mud or food on your face. Or a boogger in your nose. Or some weird growth. It’s nice to have a full length mirror: to see how your outfit’s looking, to check if you sat in dirt and to check if you’re gaining or losing weight.
Many places I’ve been in Africa have not had mirrors! In America, it seems that they are everywhere. Certainly everyone has at least one decent one in their home, and I’ve always had several.
