Hands

Four trendy teenagers sitting across from each other in pairs, chatting with each other silently. They are using sign language. What strikes me about this more than ever is the sheer eye contact and interaction between them. They are invested and engaged. They aren't idly looking at a cell phone half-listening. They are intently looking at each other on a conversation. 

It's remarkable. Their "disability" has made them more respectful communicators than people their age will ever know. 

I hate to stare but am genuinely jealous of their dynamic.
