The world of the friend-failed is unfortunate. They have every intention to befriend but they missed social queue. The friend-failed often have to undergo social boot camp, including instructions from their friends and others who are more socially adept at interactions than they are. The friend-failed would do well to heed the advice of their companions and those around them, including their parents, to whom they probably weren't listening, and that's why they're socially retarded in the first place.
"I just totally friend failed, I haven't attended 10 invitations in a row to party by this girl. She'll never ask me again, I've lost my access to this new social circle entierly."
"Who doesn't wanna party? Why didn't I say yes? I'm a social retard, I just friend-failed."
