There's no reason to feel bad about this. All things pass, in time. We're only here for a short amount of time, in this particular configuration. You, me, every possession you've ever owned, every home you've ever lived in, everyone you've ever met — everything is a temporary configuration of energy and matter. Everything changes. How well do you dance?
Now a cartoon! ☺
The only freedom which deserves the name is that of pursuing our own good in our own way.
