I've been making edits to a document on my computer while referring to a hard copy of it in my left hand, so I was hunting and pecking with my right. I finished typing a sentence, and I hit the space bar twice in a row to produce a period (which is a feature on iPhones and iPads). It didn't work, so I tried it again. And again. And again. I probably did it about five times before I realized I was using a damn computer keyboard and that's not how damn computer keyboards work, Esmerelda, you idiot.
The only time I write by hunting and pecking with my right hand is on my iPhone and iPad, and I do it a lot. 80% of my comments are written that way, probably. And now it's in my muscle memory, and I kind of feel like a sad goober.
