This little grammar war has been taking place on the walls of our department corridor this week. There is much speculation about who wrote the typed response—it looks like it must have been a faculty member, but no one is admitting to it. (That could be because of the words "pedantic" and "prick" that other faculty members have been bandying around ever since it went up.)
It's especially rude given that the original sign-writer is also a member of the department, and therefore the anonymous response is by one of her colleagues.
I just can't believed they cared about it this much. Whew!
(I've also been amused at the number of students I've seen taking photos of the sign. Some even admitted they are putting it on Facebook or on their blogs.)
