If you see something that bothers you or you witness trouble, don’t complain because unless it’s happening to you, it’s none of your concern. If you’re sense of righteous indignation is raised, squelch it. Don’t interfere. You should turn the other way. Enjoy yourself. Read a book. Have a beer. Do something fun. If others are suffering – hey, that’s their deal. Why should you involve yourself? You’re not a party.
