Okay, I would let the past go but correct me if Im wrong...
I dont see the point in holding onto such things at this point in his life?
Why hasnt he deleted them already?
May be he is lazy to do that, I myself haven't deleted any emails from my inbox, sinece yahoo and gmail are providing with unlimited space and options to search the mails, why should i be bothered to do that, he can be little bit unorganized and thats all. why to make an issue out of it?
