I don't understand?

So today I was pondering about Elias and some other things and I began to wonder...why people just pick up and leave...

Is it because they're inherently bored? Because they want to go out and explore? Or is it simply an impluse they give into? A spur of the moment compulsion to dare the world to end them...

It's ludicrious. I find these people disgustingly selfish...you are not JUST YOU. you will never be JUST YOU. You are, at your core, a compilation of people who love you, and people that you love back. I just really don't understand it at all...

how can you do that? Do these travelers just not have any kind of empathy or thought?

I don't understand...I just don't understand...
