Exactly, the effectiveness of this approach is in question. The MORE PERSONAL you make this the more serious they are going to take it...
The other question is :
What are you hoping to accomplish? If you want him to DO something hedge your bets and knock on the door. If you just want to get his attention then the letter may do that...
I think if you sat with him and even waited til his wife gets home... he will confront her
"This woman says you are cheating on me and sleeping with HER HUSBAND?"
She will deny it of course.
BUT... he MUST suspect... she isnt' likley sleeping with him anymore, and she's in and out at late hours... being secretive, antagonistic and moody...
You showing up at the door may just confirm some suspicions.
If I got a letter at my door I wouldn't give it nearly as much attention as a person who had the courage to knock and speak to me in person.
AND, if you ARE doing this for HIM because you feel he has a right to know.. don't you think he should hear this in PERSON?
Better question... how would YOU WANT someone to do this if it were YOU?
WOuld you take a letter half as seriously as someone knocking at your door?
