21 | Kirsten O’Brien & Tim O’Brien
TV presenter Kirsten O'Brien and her little brother Tim had a globetrotting childhood, racking up the airmiles following their engineer dad's career to some pretty far flung corners of the world. Living the ex-pat life made them close and gave them a world view way beyond their native Middleborough, where they were the first people to have a microwave and a VHS. The pair scrapped and fought a lot, something Kirsten - as a self-professed "wind-up merchant" - takes full responsibility for. However, as older teens their shared indie-kid identity brought them close, a bond which was tested by the grief which followed the death of their mother when she was just 54.
