In my travels, I drive past countless small air fields with signs reading: "Hangers for rent". Usually, there is nothing I can do. But one time, there was an easy-to-remember e-mail address on the sign.
When I got home, I e-mailed them a friendly spelling correction. There may have been a mild element of sarcasm, but nothing cruel. It's such a common mistake -- but I kind'a figure people ought to know how to spell their own business.
There was no response to the e-mail, but on my next trip I saw that they were now in the business of renting hangars.
An English major's got to do what an English major's got to do. Thread drift over.
