Am I very unreasonable to hate them?
We have a road that I travel on quite often, it's locally known as 'Death Valley'. It's been the site of several fatal accidents, namely because people overtake and misjudge the traffic in the opposite direction.
Anyway... some of the lampposts are absolutely festooned with dirty and torn teddies and dead flowers and banners and goodness knows what... until mothers' day, birthday, Christmas or some other memorable day results in even more stuff being added. Some of these accidents happened five years ago or more. 
This isn't common all over the UK, just in spots. I've often seen a cross on a verge, with perhaps a small wreath but nothing on the scale of 'Death Valley'.
I drove past one of the 'festooners' today, putting some garish finishing touches to a memorial picture (the size of a dartboard), with fairy lights. She was darting across the road and I think it's a matter of time before she becomes part of the tribute scene.
It goes without saying that I feel dreadfully sad for the bereaved families but WHY exactly, does the accident site have to become an impromptu display of ostentatious grief? I really hate it...
