My daughter is not exactly friendly from the start. I think (hope) her stand off-ish-ness and hesitation to greet people is born of a shy nature and not a general dislike of humans. Although when she RIBBITS at women in line at the restroom I get a little nervous.
Anyhow, last weekend at the pool she was swimming around and in such a great mood that she greeted two separate boys as follows:
to the first: "Oh HI little friend!"
to the second: "Oh HI little boy!"
In both cases she was ignored. So now I can blame her general dislike for people on an early childhood rejection experience. Phew.
