Everyone defines themselves by their role

I don’t and I bet many people don’t as well. I define myself by what I know, who I know, what I believe, like and dislike, have done and can do. Roles can be assigned, but they only serve as oversimplifications of what’s expected of people. The role of “mother” only means that a woman has one or more children. Whether said children are blood related, adopted, whether she’s a “good” or “bad” mother, whether she’s married, widow, single, etc etc, is up in the air.

Your second argument there doesn’t need roles to be answered either, or do you think only specific roles can help people? Life isn’t an RPG with clear-cut classes
