Here is a record of a real email exchange between Professor Hans and a student:
Student: Someone left a stethescope in the van coming back from the hospital - maybe
you could send a message to the class about that?
Prof: OK, I just did. But for my benefit, what is a "stethescope"?
Student: A stethescope is used by doctors to listen to ones heart and lung sounds!
Prof: Oh, that would be a stethoscope, I know about that. But you said you found a
stethescope - and I still don't know what that would be!
Student: Haha, I see my spelling error! Sorry!
Prof: Ok, all clear. But just to be picky it should be "one's" instead of "ones".
Student: OK, thanks! If we had to go through all our mails and texts with a spellchecker
we would have little time for study!
Prof: (to himself): "Spellcheckers - alright, those are for typos. But how about knowing
some English, Hair Doctor?"
(Of course, it is a standing yoke that docters do not wright and spel good. If KMC had
continewd to eccist, we mite have stahted an englisch cuarse!)
