It's hard to imagine now a world without Facebook (even though we were living in that world just a few years ago), where young people didn't necessarily have this public outlet for their emotions when faced with tragedy.
The nature of online tributes is such that those paying respects feel like they're talking to their friend as much as sharing memories with others. Hayden Miles' friend was reported as saying: "We have a right to have pages where we can write messages for Hayden."
And the outpouring of grief in this manner can only be seen as healthy and welcome, as opposed to bottling it up or venting through antisocial behaviour.
We can all only hope that we're never in a position to be mourning a friend taken before their time, but should that be the case some of us would very much appreciate the opportunity to pay our tribute in such a public, and at the same time personal, way.
