Waving hello?

It's one of those things we're not quite sure about, but she might have waved hello today. Seeing Abba when he came home, she smiled and moved an arm towards him. Coincidence? Maybe.

Earlier she did the same when a visitor walked in, a stranger. Come to think of it, her earliest smiles, the subtle ones of her first week, were also elicited by strangers. Does this mean she won't be a shy girl?
