“Simply looking each other in the eye can make a big difference. Failure to make eye contact, or perhaps, worse still, failing to look with interest into someone’s eyes, diminishes our sense of connectedness. When there is no eye contact or when there is no interest shown in the eyes of the person who gazes at us, we feel like we have been ‘looked through’. The Germans have a phrase for this—wie Luft behandeln—which translates as ‘looked at as though air’. When we are looked at in this sort of way, it can be quite hurtful.”
