Accidentally opened someone mail

Tape it shut, mark it "Return to sender, no such person at this address, opened by mistake" go to the post office and put it in the big blue mailbox. No problem.

 

Do the right thing and send it back. It's not junk mail it's important.

 

I wouldn't have opened it.
Had I opened it by mistake, I would do as adjuster jack suggested.
That said, only the two of you know what was done.
Let your conscience be your guide.

 

If you ignore it you're bad people.

If you send it back you're good people.

It's that simple. Your choice.

 

I agree with the others who said to mark it and put it back in the mail. It wouldn't cause you a problem if you just ignored it, but it might cause issues for the poor unsuspecting person it was addressed to if they didn't respond to it, so in my way of thinking, returning it is the decent thing to do.
