I'm going to do that now. So we don't know why the Indus Valley civilization ended, but we also don't really know why it started. Why did these people build cities and dig swimming pools and make unnecessarily ornate seals? Were they motivated by hunger, fear, a desire for companionship, the need to be near their sacred spaces, or a general feeling that city life was just more awesome than foraging? Thinking about what motivated them to structure their life as they did helps us to think about how we structure our own lives. In short, you're clingy because you're motivated by fear and a need for companionship. And she finds it annoying because it's enough work having to be responsible for herself without having to also be responsible for you.
