When I was 16 I chose to leave school and start at a Sixth Form College that was 20 miles away from my home. The college had several housand new student starting, all of which were integrated into existing form groups made up from 12 students from different year groups. On my induction day one of the new students in my form group approached me and seemed to know a lot abbout me, he knew my hometown, that my mother was Irish, that I had family who lived in a specific part of County Cork... What started of as general information seemed to get more and more specific, something that was very strange for someone that I had never met before, had never attended any schools, clubs or functions with me and didnt appear to know any of my friends. When I asked him how he knew so much about me his response was that his brother was engaged to be married to one of my Irish cousins.
My cousin had moved to the UK to attend university in Yorkshire where she met her husband, once engaged they chise where to live and ended up in a property 10 minutes away from my parents (who they simply knew as "living in the UK").
