It depends on whether the laughter is about the game itself or some personal experience a friend has shared over VC. Cause the loudest room on our dorm floor was always the League+Melee room, and it wasn't cause they were sharing funny stories, it was because Falcon did a moonwalk short-hop reverse-knee fast-fall L-cancel.

They are laughing because someone got killed by Glitch. Fortunately I do have conversations with my kid.

I laugh at the funny HN comments. It is still a solitary activity.
