If you see a sign (or something similar) with a grammatical mistake in it, take a picture of it and send it to IJudgeYouWhenBook@gmail.com with the disclaimer:
“I, [name], give permission to Sharon Nichols and St. Martin’s Press to use the picture I uploaded to the Facebook group “I judge you when you use poor grammar.”
If we use your picture, you get a shout out in the book. We have until July 1 to collect the pictures, so keep taking and sending them. Thank you to everyone who's participated so far, and happy hunting!
