My heart goes out to all those who lost loved ones that day. I know all too well what it means to lose a partner suddenly and without warning. The public outpouring of grief and support may have helped at the time but I do wonder what it's like now that many years have passed. Surely they don't want reminding of that pain every year.
I think it may be all very well for onlookers who want to have a sentimental wallow but for those who were actually involved, who lost loved ones and colleagues, it may be making it hard for them to move on.
