Sally's stalker

Sally has got a Liberian phone stalker. He first phone call woke us up at 12.40 am three nights ago, and he has since phoned about 30 times all through the day and night. Sally has saved the two phone numbers he uses as "Nightcaller" and "Idiot 2" so we know when he calls. This morning I had a nice chat with him, although I didn't understand him and he didn't understand me, but I enjoyed using up his phone credits. He's not phoned back since. Maybe that's the end of a beautiful relationship...Olly
