Let me add to the amazement by pointing out that there even seems to be "Price is Right fanfiction" out there [0].
Tho it's hosted on angelfire and the texts are saved as word documents, which is either really odd or really smart, depending on the intentions of the creator.
You "corrected" someone out of ignorance who knew your correction was wrong. I think you need to swallow your pride rather than complain about their being condescending; feeling humiliated is your brains way of learning to be more careful in the future.
I expect I made a mistake here too, that would be normal in this sort of conversation.
