Today is National Grammar Day

And Geoffrey Pullum has a great post over at Language Log in recognition.  He briefly (and correctly) touches on my pet peeve, the careless substitution of the word that for the word who, as in "I’d like to meet the person that painted this picture."  That is for objects or animals, who is for people.  Folks who pride themselves on being sensitive and considerate blithely reduce their fellows to the status of pets or furniture every time they speak.  How rude.
