There is a lot going on while moving underground. There are groups of hundreds of people, sometimes even more, waiting to get on a train, moving on the stairs, struggling to get their luggage inside the carriage, others holding hands.
The world of those who love is very small. It ends right behind their loved ones. They stretch this world while holding hands and brighten the day with their smile. They stand out in any crowd. I see them and I am happy.
