Obviously, it’s not just that Perrette had a long career herself in the entertainment industry, but that she had a steady gig on a very popular show where she gained a lot of fans, which would lead a lot of people to try and get into her good graces. Fifteen seasons is a long time to be on one television show, and she surely made connections there who could help others get a leg up in the industry.
Perrette has always seemed like a pretty kind, generous person, so she probably has tried to help people out along the way, but that doesn’t mean she would be happy about someone only getting to know her (or staying in her life) because of what they thought she could do for them.
