Had an old school friend I hadn't seen in nearly 25 years as a kid I spent most of my time with him, found him via facebook and we agreed to meet up in his home town.
First problem the area he lived in was in the red light district, pub was very run down but hey ho....
Meet up with him and regretted it within a few moments, on his 5th divorce married every 4 years, self opinionated, boarderline alcoholic and long term unemployed (subsidised his income by selling his wifes meds on the black market).
It was such a shame, wish I had never done it.
