She was trying to understand what was happening and explain it to me, but she was also somewhat scared of what was going on. One of the few words I understood was "suicida" because the boy was talking about the tragedies in his life and how he didn't want to live anymore. When he started hitting his arm against the glass, I thought he was going to commit suicide right there. Being our first time using the metro, we decided at that moment that it would be our last time as well.
