lol

Back in the day, you had to make sure your message was worth it. With the age of instantaneous communication, we've definitely devalued single messages.

A similar conversation in 1998 would have gone a little differently.

Sakisenpai: "lol" Shawn: "You and those damn acronyms... can't you just say 'ha ha that is funny?'"

(it took "lol" and "wtf" a while to become common use, too)
