We have a Requiem liturgy (with Faure's Requiem for the last couple of years anyway) on this day at our church every year. In Paradisum is just glorious.
There is one couple that we know lost their son, we don't know how old he was, and I knew some of the other names that were read out.
I was discussing annoying journal editors (bear with me, this is relevant) the other day with a colleague and some of them are extremely pernickety about whether they have got approval from every single co-author. I had to tell one of them "you aren't going to get anything from him. He's dead". As they would have known if they'd read the acknowledgements.
As well as our four losses, I thought about my mentor, who died at 50 from pancreatic cancer; my grandparents; one of our former project workers who died in a car accident (the most common cause of death for young adults in some African countries) and the five, at least, former project workers who have succummed to HIV.
