I have a good, intelligent friend who butchers everyone's name, including mine. We have been friends for 2 decades.

My last name is not hard to pronounce and after 20 years, my friend should be able to spell it correctly. Oh, she doesn't spell my easy first name correctly either. It used to offend me, but then I realized she has this problem with everyone's names. There is just some disconnect with the part of her brain chamber that deals with names. Perhaps your T has this sort of disconnect also.
