We rely on the expression around the eyes with our partners to connect. It tells us if they are feeling safe or happy or worried or threatened. Without this cue we don't know how to respond. We see this in children with autism who have flat muscle tone around the eyes; not only are we unable to understand their social engagement cues, but they are not able to understand ours either.
