Odd letters in the mail.

I would talk to the postmaster and have the postal inspection service ask the person to stop. It sounds too much like stalking to be taken as "sweet".

I would avoid contact with the person yourself, as the postal inspectors occasionally meet some "interesting" people when handling issues like this.

There are some things that you just shouldn't mess with.

Yes, the postmaster for sure - and talk to the women he may be trying to reach. I am sure you will get some VERY interesting information!
