I had a mad one who would phone at bastard hours after I chucked her and just screamed down the phone. I would never stalk as I never had to or would consider anyone worth the effort. It’s a mental illness and one of the few I don’t possess.
I've seen some disturbing traits down the years from the ladies. I didn't get a mobile until I was 17 so most of my extra curricular schmoozing was done at the PC, girls from school and all that. I can remember my nan ringing me to tell me that a girl from my school had rang her house after hunting down our surname in the phone book and seeing the area of Manchester, putting two and two together. That one was fairly endearing. There was a total psycho a few years later who used to message my relatives on Facebook if she saw me out and about after we split up.
