"We’re a social species, which means we need each other. So instead of avoiding strangers, we need to get good at interacting with them, both to get help when we need it and to be of use to them."
"Let’s start with actual strangers — like the people you pass on the street or in a store. You may not think you’re in a relationship with them, but you essentially are.
"Research shows that when you look right through someone as if they aren’t there, they feel a small sting.
"The reverse is also true. When you give someone eye contact and a smile, it demonstrates 'You exist, fellow human, I see you,' and it makes them feel good. And you feel good too when they do it back to you." - Julie Lythcott-Haims
