Delayed Wave Reaction
Adrianna has learned how to wave at others and she does so quite often. However, her reaction is often delayed. Strangers will come up and talk to her and smile at her and then wave bye-bye. She smiles back at them with no problem; she is such a smiley and friendly little flirt. About 30 seconds later, she then starts to wave. Of course, by this time, the persons she is waving bye-bye to are long gone and do not get to see her little waves meant for them.
She also waves backwards. The palm of her hand faces towards herself rather than outwards, so that when she waves, she is waving inwardly. It is quite cute. I guess that is how it looks to her when others wave at her, so it really does make sense as to how she picked up that little habit.
