Can't even pretend

If a picture is worth a thousand words, than Lexi's expression is speaking volumes about how she feels about a kodak moment with mom. What are some of the thousand words she is trying to convey? I'm picking up: bored, apathetic, could care less, can we make this quick, dull, annoy, etc, etc...
Looking at this picture makes all the mundane aspects of being a mom somehow worth it.
