You don't hang the instructions on how to cut and paste a video on answermug to the front of it. This is NOT good. You must find a thumbtack and stick the instructions to your kitchen wall. You don't feel obligated to hang pictures of your grandkids on the front of it. You know you can live a happy, uncluttered life in your kitchen because of it. There are millions of positives to this newly found benefit. I say, keep the refrigerator just quickly find a new place to post your answermug instructions!
