I for once agree with Legend. I contacted a long lost friend last year.
We grew up together and into our teens she was always causing trouble, being 2 faced, telling tales to our then boyfriends.
I dropped her by slowing phasing her outa my life.
But last year, I found her on the internet as she now has a good job.
Invited her round one Saturday and she managed to create havoc. Telling Mr Funny what I was like in my teens (you know the bad stuff), flirting with him. She had not changed.
I have not contacted her since!!!
