I walk along crowded streets but people are not there with me but connected with other people through mobile phones which allow them to talk or send messages.
They should have strong feelings with these people. Maybe somebody is making some of these pedestrian cry.
I know that some couples are being broken and new lovers are starting their relationships. I can imagine business which are closed and people who are hired or fired. Probably, some of these messages informs about a beloved person's death.
A lot of universes in this bustling avenue.
