im so tired

-Why are we acting like that anger, fear and joy are the only emotions that exist?
-Why are we acting like Alex has never seen anyone feel joy before, ever, even for a brief moment? I mean her life was hard, but I can't believe she has never seen a single person walking on the street, feeling joy.
-Why does the game expect us to care for the characters when we have such a short time with them?

!!!!!!!!SPOILERS!!!!!!!!!!!!!!
-Why doesn't it matter if you befriended everyone? The ending is still the same, it ruins the message that community is everything.
- Why should I believe that Alex not only survived that huge fall, Jed missed a head shot from like a 1 meter distance, Alex could walk after all of that, and got out of the cave?
