The common wisdom is wrong. Of course personalities develop after 7 years old. People's personalities develop well into adulthood. Adults are capable of developing, continuing to mature, and changing their behaviors. Who I was at age 7 is not who I am today. Who I was at age 18 is not who I am today. Do people really think that anyone who fights with a sibling past the age of 7 is destined for prison? I guess I need to start making a plan for when I'm arrested.
