I observed

What do you do when you do nothing?
You just sit there smile at your phone. Maybe the beloved one sent you a message saying 'What are you wearing?' Well, you are in your winter coat, you have a hat and a scarf, but you type back: 'Lace' and giggle a little, hoping no one sees you are blushing.
Or... you are smashed in between a shy blushing girl and a man reading a pretentious novel. You need space to take off your phone, because you have at least 30-minute-travel and the boredom has taken over you. Jelly splash or Candy crush? I'd say they are the same.
That's your newest book? It's not quite what you expected is it? Thinking of the work meeting you are late for because of the traffic and not being able to concentrate on the story of a murder in the novel. You hate loud music.
Yes, that fat guy just stood up, you should definitely sit on the free spot and turn the music on. The new album of Arctic Monkeys is amazing especially when loud. That's how you escape your problems, you can't even hear your own thoughts because of the song.
That is how I see you, train people.
I am there and I am just like you, but I don't feel like I am part of your society, I feel different, despite the fact I do everything like you: I don't ever leave my phone, my music or my book. I dress in common way, I chat, I talk... I am no even quirky in any way, but I am not of your kind. I am still searching who I am.
