Out of the 26 letters of the alphabet, only 14 can be still be viewed. The others have been rubbed away from frequent typing. Forget trying to find a vowel, they were the first letters that went.
Yesterday I noticed that the letters "a," "s," and "l" are wrinkled. They look sort of like they've been poorly shrink wrapped. Did I wear down the keys? I have no idea how that happened.
Thankfully the markers on "f" and "j" haven't worn away. In high-school I took a class on how to use an electric typewriter. Thank goodness for Word . . that's all I have to say. I've never used a typewriter since, but I learned to touch type.
Most writers I know touch type as well, though I've met a few who don't.
How about you?
