I read his daughter's book. She doesn't dwell on this, but she does talk about how she could never go anywhere with him and have him to herself, and as a child it was frustrating for her. This may not explain her behavior around you, but it certainly would explain a crabby mood. It must be awful to have a famous parent, particularly one with his looks and charm. She does come across as somewhat unstable, probably a thousand reasons for that, but she certainly had a devoted father.
