There’s this person on another forum that is constantly making typos. A couple of times, I pointed it out to him and he’s always said that he was in a hurry or tired. Then it occurred to me that I might be unknowingly poking fun at a dyslexic. 
Would a dyslexic person misspell next as “ewxt”?
Given that the E and W keys are right next to each other, you don’t need dyslexia to hit them together and have it come out “ew”
Is the co-worker naturally left-handed? Maybe he just doesn’t have as much strength in his right hand. Maybe he hit the space bar instead of the N.
Take it from someone who went down in history as the worst person in the history of my high school’s typing classes, there are a lot of ways to make typos without being dyslexic.
Ah, makes sense. Still, he almost always has typos in his posts, even short ones. I guess that he’s just a really hasty typer then.
He’s not a co-worker. Just someone that posts at another forum.
