Great eye to spot this moment in time showing contrasts in 'connectivity'. The two on the ends are 'plugged' in to their electronic devices - socially they are disconnected from the world around them. While in the middle are two women who are speaking with one another face to face. Also interesting how the two on the end that are on their smart devices are devoid of expression while the two chatting women are very expressive: one asking has an inquisitive look and the other is smiling. Your B&W tones and details of this shot are wonderful!
