I am outsmarted by a 2 year old!

Grammy and Avery, who is all of 2 fingers old, were snuggled on the couch reading books together.
Avery had trouble saying some of the words from the book and Grammy was helping her. Avery would try and repeat them then. And try she did and would smile and giggle when Grammy told her how well she did.
But Avery had trouble saying the word "Grammy" itself. No matter how hard Grammy told her to say it, Avery came up with something else.
So, Grammy in her teasing way, and poking a tickling finger in Avery's belly said to Avery "say Gram-Me, Gram-Me, Gram-Me", sounding it out so slowly so Avery could hear it and then say it. Well, Avery looked up at Grammy and took her own tiny finger and poked it back at Grammy and with a big smile said "Gram-You, Gram-You, Gram-You"!!
Avery could not say "Grammy (Gram-Me) because she thought it meant herself! So, now I am a Gram YOU!!!! (you you you)
And how smart is that??
