I was writing some notes in Braille today. As usual, I was using my BIC pen to emboss Braille letters. When I finished, I put the pen on the table, but then I accidentally knocked it off. I have a thick carpet on the floor, so I didn't hear where the pen fell. I had to systematically search for it until I finally found it. If you can see, you just look for the pen and pick it up. But if you're blind, such a simple task can be quite time-consuming. Sometimes the smallest things are the biggest obstacles...
