Dear Firefox 3,

You have recently informed me that “didn” is not a word, by the subtle but helpful act of underlining it in red everywhere I use it.

I believe there has been a misunderstanding.  I agree that these letters alone do not constitute a word, however when followed by an apostrophe and the letter T they form the contraction “didn’t.”  This is completely valid, and might be used in the sentence, “Didn’t you learn about contractions in the third grade?”

Admittedly, the character Data in Star Trek: The Next Generation famously could not use contractions, but I regret to inform you that nobody (outside the show’s production staff) ever found this remotely plausible.  If you can learn 170,000 English words, you can learn a few others that are spelled with apostrophes.  This applies likewise to you, Firefox.  Please do not make this error again.

Sincerely,
B’n
