I hate it when people are like "You know, trying to survive"
I usually just say "better than you" and then they inquire which starts more of a conversation.
I'd say "You know that feeling when you're tilting back in a chair and you tilt too far and start falling but then you catch yourself? That's how I feel."
i usually say "AWESOME" even if I'm not awesome because i like how they go O.O
I usually say I am absolutely fantastic, or just wonderful. Or something along those lines.
I normally say something ridiculous like "Good cause I stopped Hitler from killing all the jews." Then they'll be like what?.........and that's how I met your mother.
