Dad: Suck it up. Mom: Get over it.
Being bullied in school doesn't mean you have to be bullied for life. As a kid, things can be stacked against you. You're surrounded by people who are older, stronger, more powerful, and more capable than you. But you don't have to be bullied as an adult if you don't allow it to happen. Adulthood is a much more even playing field than childhood. You have resources (HR department, change jobs, change neighborhoods, police, social services, lawyers, etc...)
I know there are people who as adults are bullied. I know some of them. But in every case I've seen they've allowed a history of bullying to make them believe that they are powerless to change their circumstances. They're not. They choose to remain in that position because it's familiar, and change and confrontation are scary. But sometimes you've got to suck it up, act like an adult, and do adult things. And that sometimes means standing up for yourself.
