You clench your teeth.
You look up.
You tell yourself that if they see you cry,
it will hurt them,
and you will be nothing but A Sadness in their lives,
and you must not become a mere sadness,
so you will not cry,
and you say all of this to yourself
while looking up at the ceiling,
and then you swallow even though
your throat does not want to close
and you look at the person
who loves you and smile.
-John Green, The Fault in Our Stars
