In theory, you may know that it's important to treat your friends with understanding and respect, but this comic by Nate Swinehart reveals the "real" reason why you should play nice with others—and it's pretty darn funny.

In addition to sharing his art and comics on Tumblr, Swinehart also created the scifi adventure webcomic leveL. Go check it out.

Thanks to Swinehart for allowing us to share his comic here.
