Ah, handkerchiefs. Most people think they are a thing of the past, but they are in fact still very common in Asia! I remember when I was in elementary school in Taiwan (I only went for six months there though) every morning the teacher would check if we had clean nails, all of our books, our notebooks, a pen, an eraser - and a handkerchief, Back in Germany I forgot all about handkerchiefs. It wasnt until I spent a year in Tokyo (and two months in Taiwan) during grad school when I realized that handkerchiefs are still very much in use. Not as snot rags, but for other odd jobs like drying your hands or wiping off smudged mascara. But why not use them for the occasional sniffles?
