One of the messages being portrayed through touch is a message of comfort. The women in the blue shirt has a gentle hand laid on the women crying, and this is a way of comforting the woman in the pink shirt. The woman in the pink shirt is also communicating that she needs/wants comforting by leaning into the woman in the blue shirt. I hope that helps!
