One role that I play is being a daughter. I’m always gonna play this role because you’re always gonna be someone’s son or daughter. Another role I play is a best friend. I play this role when someone needs a shoulder to lean on. And a granddaughter. I will always play the granddaughter role.
I hope this helped! :-)
