A world where people have the ability to respawn right after they die , but ...

My first death was when I was eight. I was skiing with my family when my ski snapped in half, sending me tumbling head first down the steep and snow-covered mountain face. Then I woke up in my bed at the lodge, 24 hours had passed, but apart from that I was completely healthy and it was as if nothing had happened. Many of my friends had already died a few times by then, why teach road safety when dying does n't even matter? 
 
 My second death was at sixteen. I was being bullied at school when one day it went too far. Boris threw one punch too many and I lay, bleeding and in agony, on the ground. It took me over an hour to die that time, I was just left there to die. No one thinks of death as a consequence when you just come back to life again. And sure enough, another 24 hours later I was lying in my bed right as rain. 
 
 My third, and so far final, death was last year. I was wind surfing with my friends when the sail hit me on the head. I was knocked straight into the water, trying in vain to break the surface, instead drowning coughing and spluttering in the sea. It all went black again. I woke up at home, safe as houses. 
 
 Today I went rock climbing with my best friend, Greg. We chose the tallest cliff in the area and climbed, not caring how clumsily we climbed, knowing that it did n't matter. About half way up Greg lost his footing, he was dangling from just one arm. Until his hand slipped and he plummeted to the rocky ground. He died on impact, there was no way he could have survived. 
 
 I quickly descended the cliff, it was no fun climbing on my own. Greg lay there, so silent and still, in contrast with the happy joking of just moments before. No matter, I only have to wait one day before he returns, that's practically no time at all. 
 
 I get home on my own. My girlfriend is surprised, she expected me to be with Greg. I quickly tell her what happened before carrying on with my life. There's no point crying over spilt milk after all, it's not like I'm not going to see him again tomorrow. 
 
 As soon as I wake up I go to Greg's house. Unlocking the door with the key he gave me I go to make sure his bed is ready for him to re spawn. I lay out flowers, and chocolate which is meant to help the body recover - but who needs excuses? Nearly 24 hours have already passed by the time everything is ready. 
 
 I wait expectantly as the clock ticks closer. The time comes and I am ready. The time passes. He has not re spawned. Where is he? Did he choose a new re spawn point and not tell me? I wait another hour - just in case. But he does n't turn up. 
 
 I leave, walking home alone and wondering what has happened to him. My girlfriend is watching the television. About half an hour into whatever rubbish soap opera she's watching the news suddenly comes on. They tell us that all around the world people have died and not come back. Something has changed and for what ever reason we have suddenly and with no warning list the ability to re spawn. So Greg is not coming back. 
 
 I do n't know how I feel. I suppose this is the feeling they used to call grief before the re spawning started. It is a hollow emptiness as if there is a space within me that should be filled with Greg. I can not speak. I can hardly eat, I have no appetite when it comes to dinner time. I spend all night tossing and turning unable to sleep. Every dream turning into a nightmare the moment I think of it. 
 
 I lost the ability to function normally. For the last few months I have been no more than a zombie, a shell of my former self. But I have finally realised that moping wo n't bring Greg back. Moping wo n't bring anyone back. So I have decided to try. To put in the effort I have not had and attempt to live enough of a life for two of us. Otherwise we may as well have both died that day.
