Picture it: You're in a hurry, you have to move on... BOOM. "Oh my, I can't believe I hit this person's car!" But I have to GO. NOW!! Here, I'll leave them everything I have on me... literally. Good enough??
When I want to introduce myself to a neighbor, I tend to bring them a treat - invite them to a gathering - let my dog run into their yard - or just have my music too loud in the garage. Turns out I could treat these folks way worse.
