When I've lost loved ones and people have told me that, it's always confused and frustrated me. But I think ultimately some people say stuff like that both because some people don't know what they're supposed to say, but based on social conventions they may feel like they're supposed to say something. That and maybe it's just a difference in personality. What I mean is like people like you and I are people who, no matter what happens or how much we hurt, we keep going because that's just who we are and what else are you supposed to do? Fall apart? How does that do? But some people do.
