I’ve never thought of myself as an athlete. And maybe I should? Because maybe being an athlete doesn’t mean doing a marathon or making an Olympic team, or swimming like Natalie Coughlin. Maybe it just means doing your best with the body you have?
Catholic NUNS are cloistered. That means they don’t work in hospitals, run schools, etc. They don’t leave their monastery unless it’s for something like a doctor’s appointment.
Catholic SISTERS do these things.
So, nuns aren’t sisters, and sisters aren’t nuns.
