This is a picture I drew digitally of a typical Windows keyboard or just a modern day keyboard. See how the Q key and the W key are so close together? It's perfectly reasonable for him to have mistyped, saying "quo" instead of "who". I sometimes check for spelling errors (especially now) so that I don't lose an argument or something or so people like you don't type stuff like ""Qho" 💔". That concludes this message that absolutely nobody cares about and thank you to the 1- people who actually read all this, and for the 0 people who actually care.
