Would you say anything to your neighbor? Would you tell him you’d prefer that he didn’t pick your fruit without asking? Would you tell him to not step on your fucking flowers? Or would you smile politely, nod, carry on a friendly conversation, and only internally react? Would you be angry, but too scared to show it, and instead wait until he was gone, then go into your house and tell your spouse, “Honey! You wouldn’t believe what Albert just did! That guy is such an insensitive, stupid jerk!” (Real tough guy when he’s not around.)
