I ask because it's almost a daily occurrence now. I've never learned to type but at this point I'm pretty damn fast with the hunt and peck method. Some letters have worn off my keyboard. E - R and T is the trouble spot becsue they are right together. If I'm just typing and letting my fingers do their thing I have no trouble finding these letters but when I actually try and look for the key...... Hmmmmmmm. And that makes it worse becsue now I'm thinking about it and not letting my fingers do their thing.
It can be embarrassing too. Years ago I'm having this conversation with the neighbor and I point to this object on the ground and I went just blank, for the life of me I couldn't remember the name curb.
