The year is 2019 and you are laughing at the pictures online.
The pictures are funny because you understand the contextual foundation of the jokes. This understanding makes you feel included, as if you're part of an inside-joke.
You look to your left, then to your right. You're actually alone.
You've felt alone for years, but the pictures online help you to forget that. The pictures online make you feel like you're having genuine shared experience.
You know deep down the experience is not genuine, because there is a void in your heart that even the freshest meme could never fill.
