In a different world
You might be asking yourself: was the boy all alone? No, this wasn’t the case. The boy was riding with his mother who was seated next to him with headphones on listening to music. The teenager was laying up against her with feet out on the bench. Even though other people wanted to sit.
The boy was so consumed by his phone that he didn’t even realize it was crowded in the metro and that other passengers were looking for a place to sit. Even his mother was too caught up in her music that she didn’t notice how busy it was. Or were they both aware but just didn’t care that much?
