My friend Carla moved to a suburban complex last year and made a point of nodding or saying hi to everyone on her morning jog. After a few months, she told me she started recognizing regulars and even had brief chats about weather or pets. She said it felt like an unspoken pact of goodwill, and when her package went missing, a neighbor she'd only exchanged smiles with actually helped track it down. It's like those tiny interactions built up a safety net without anyone realizing.

Isn't teaching incomplete just glorified guessing?
