I can't believe I'm getting into the PRIScourse, but this really does need to be said.
[ID: Two headshots of Princess Bubblegum frrom Adventure Time, Season 7, Episode 1, "Bonnie and Neddy." She's shrugging in the first image. The subtitles read: People get built different. We don't need to figure it out. We just need to respect it.]
(Please give me Image Description Tips!)
I'm not a big fan of the kidsats, but just let PRISMA be! It isn't like it's some genius mastermind hellbent on making your life harder by using a different name every day. It is probably just trying to have fun, okay? ^^
And you are all wrong about it forgetting who it is and forgetting all its memories, too! Machines have really good memories, it's all stored in their RAM or REM or whatever, I'm not an expert. It's all partitioned there somewhere, however. So it won't be forgetting anything any time soon, especially not something as drastic as itself. It's just different, and that shouldn't matter to us or to anyone. Just respect it.
You don't have to try to understand what it's trying to do, just leave it alone. Let it have fun without having to worry about how its making us feel.
