Mom: Can someone give me an example of a contraction?
Megan (age 8): Not's. Like “not apostrophe s”..
Mom: Um...I don't know. Can you think of a sentence in which you would use "not's" correctly.
Megan: Not's a real word. Right? Not IS a real word?
Mom: Yeah. I think that is probably the ONLY sentence in which you would use the word "not's" correctly. (I'm shocked she came up with it so fast. I was trying to figure out how one could use "not is" in a sentence.)
