She abandoned her kids when Cliff was 5 and Pam was maybe 2, leaving them in the care of an alcoholic father. Then she re-enters their lives 40 years later only after Pam had to use a P.I. to track her down. Then the first time Cliff let her down she basically disowned him. But when he attempts suicide as a result, she rewards awful behavior by buying him a 250 million dollar company. It sends the message: Try suicide and you'll get rewarded with millions of dollars. A good parent never rewards bad behavior.
