My brother died when he was 20, I was pretty angry about that.
A quick explanation of why: My brother was at the time very badly off financially, he had just moved into a run-down caravan (trailer home for US viewers) It had electricity and gas, but no heating whatsoever. In desperation he had rigged up an old motorcycle cylinder on the stove to act as a radiator. But what he didn't know was that all the ventilation slots had been blocked. So you can pretty much guess that the next two words are Carbon Monoxide....
It was just kind of senseless and pointless waste, and after years of not understanding what he was about, I had begun to understand him. He was essentially a hippy, but in a good way. It was him that got me into Led Zeppelin and the like, because although he was younger than me, he had done more interesting things....
The funeral was also a revelation, because, although I thought I knew him and his tiny circle of friends, about a hundred people turned up out of the blue at his funeral, mostly bikers, hippies, and hells angels. He must have made an impression on a lot of people....
As for the grief, well, it was just numbness for about a year, then it all came out and after that I felt better.
My parents never talk about him, ever....
Even after all these years have passed, I still remember him now and then, RIP my bro....
