So was in the bookstore the other day when my bladder spoke up. Now this is not great by my figuring. Bookstore bathrooms do see a lot of use. But you gotta do what you gotta do and when you gotta go you gotta go. So I made my way to the bathroom, found a stall, and appeased my whining bladder. Then like any sanitary person I went to wash my hands. Water, soap, water, followed by three shakes from the wrist. With hands still damp I turned to find some drying stuff, a paper towel maybe. There were no paper towels just one of those hand-dryer air blowing things. I put aside my usual distaste for these gadgets, hit the button and commenced rubbing my hands as per instructions. It was at this point I saw the other sticker on the dryer. This one rather than giving me directions on how to use them told me why these gadgets are great. I read it. I told me that I was saving trees. I stopped. I felt a last drop of water run down my wrist. I read the sticker again. Saving trees. I�m sure that you have heard this claim before. You may believe it or you may not. I don't. But I don't usually pay it any mind. So why did I stop and stare and this commonplace sticker? I WAS IN A BOOKSTORE.
