Daniel, born September 11
Daniel was born on September 11, and after the events of that day in 2001, he jokingly complained that his birthday had been ruined forever, because it would always be first and foremost the anniversary of that day.
The problem only came up once, in 2002. Daniel died on 18 November that year, also at the top of a tower-block, when his apartment caught fire. He was 26, and those few days.
It's been six years now, and the hole he left just doesn't get any smaller.
