My friend chewed out the mailman because she received someone else's mail. To her, it was just unbelievable that the post office will make mistakes. Her fear was that she receives 2 rent checks monthly in the mail, and they might end up in the wrong mailbox. I told her that most people will just put it back in the box with the flag up. But, she said that she just couldn't accept that. People are dishonest and would steal it, and then went into a tirade that the post office needs to fix this! Like it's a new problem...
Unfortunately, she tends to be someone who thinks she's allowed to make mistakes (at work) with no one allowed to correct her, yet it's unacceptable for anyone at anytime in any business to make any kind of mistake.
Me, I tend to try and think the best of people. Have I been burned? A few times, but nothing that ruined my life. Do I accept responsibility for misplacing that trust? Yep. It's too tiring for me to be so distrustful of people, companies, the world, etc...
