You miss who you were when everything looked like this.
You were young, you were discovering the internet like a new frontier, every new app you tried or new album you found or new comedy website was like discovering a new country. You could while away hours without responsibility or care or trauma, or at least nearly as much. You were not cynical and jaded yet.
Nostalgia isn’t a longing for when things were simpler, it is a longing for when you were simpler.
