Then they need to be re-directed and vent the anger and frustration that they feel in a productive nature. It is not a stable environment when they come home to an empty house.

Inherited traits have a big influence on personality.
The most obvious, of course, would be the physical resemblances. Some children will accept this without question while others will resent the fact that they look the same as other family members.
