I caught out a 'partner' I suspected of not being faithful.
He edited a magazine, and had a 'partners' section.
I got my friend to write a short advert:
''Superslim 27 yr old, Long brown hair, attractive, seeks that special someone to drink wine by the fire with , while toasting our tootsies''.
I used another, rural address. {The 'girl's rural location was why she hadn't met anyone}
Anyhow.......... He came to spend the weekend here and showed me a new pen he'd bought, and asked if I had any ''purple paper?''
..I said 'no, but I have white'...Then I realised.. days later!..Friend had written the letter on purple paper!
Sure enough...Friend at the rural address got a letter with a copy of his magazine, and he said ''I know what you mean, bu looking for that special someone...I have also been on my own for years
When he phoned me, I said ''I get the feeling you are interested in other women?''..He said 'You're paranoid'&c&c
I finished it... and he kept pestering to come and stay..I just said ''NO''.
Friend in the rural location panicked in case he turned up...So had to get out of that one by saying she was no longer looking for a partner.
