While in the middle of a conversation with my mother (on the phone) I absentmindedly opened another person's mail, their W2s.
It's the kind of envelope you rip the perforated sides off of, there is no neat way to tape this joker back up. Immediately upon seeing my mistake, I closed it, I did not look at any of his information. Should I close it up in an envelope and drop it in his box? Enclose a note apologizing for my mistake?
