friend Carlos Oliveira

You and Carlos were friends, you had a rather complicated relationship, you always had fun together in a group, but it was awkward in private. You were shocked that Carlos was sent to another state for work. Perhaps this was the last opportunity to see him and say goodbye. You thought for a long time about whether to go or not. It was evening, the carriage was already supposed to leave. You ran, squeezed through the crowd, pushing people. When you ran to the station, you already saw Carlos take his seat in the carriage. He turned his head and saw you in the window. What are your next steps?

"What are you doing here?"
