Someone who I would've considered a mutual friend got done for armed robbery whilst we were still in sixth form. (17yo)
My next-door neighbour got burgled, could have been me but we got an alarm. These things happen though.
My dad, when I was 10, got dump-tackled after a game of rugby when he went for a drink at the mess' bar. His head caught the corner of the bar and he suffered concussion. Just as he's leaving the hospital the next morning he mentioned he felt pressure in his ears. Luckily the doctor heard him and rushed him in for a CT scan. He was suffering a brain haemorrhage and had the doctor not spotted this, he would've been dead by the end of the day. Despite this he's had several promotions in his job since, but he does suffer with some short-term memory loss at times.
When I was a toddler my parents refused my grandparents to take me to the states for a holiday. They were involved in a head-on collision with a speeder on the way to the airport. They suffered broken bones and to this day I don't know the damage to the rest of the car. Probably for the best. I waste no sleep on this one because one change to the past can change events in the future. If my parents said yes, my grandparents car could've left later, missing the collision.
But hell, I'm sure people have had worse. So no wasted sympathy on close calls for me ;D
As for my geographical area, an expecting mother was stabbed repeatedly, then her house burned down a few weeks ago. A few weeks before that a husband who was separated from his wife waltzed into her hairdressers with a shotgun, let rip and injured 2-3 people, then walked into the woods near my housing area to top himself, burglaries happen all over the place and it isn't Newport if there aren't druggies pleading you for money around the city centre. Not to mention the rapist who got thrown in prison after raping a teen girl by the train-station. Other than that it's a nice area though, minus the monthly high-speed accidents on the 70mph duel carriageway by my house.
