Jenna's gesture was cute and charming. Compare that to Kerry giving that vet the finger.
For a five year old.
Yes, you can tell she's joking around. After reading a thread (the day it happened) where some freepers were chastising her, I pointed that out, and sure enough, the next morning I heard that reporters with her and she had been joking around and she playfully stuck out her tongue for a sec and then they all had a good laugh.
Needless to say this article is snide. And notice the implication that Jenna is just pretending to an interest in charter schools. And the headline? Speaks for itself.
Some people are just not nice. Jenna appears to be nice. This reporter (who I've seen before and can picture), does not.
