They go to people who are disappointed, perhaps worried about the loss of money or impact on family, stick a microphone in front of them and ask for a reaction.
I haven't read the article, but unless the couple are saying that their case is more upsetting than people losing loved ones or getting married in wartime then I don't know what that has to do with it. People can be disappointed without thinking that it's the worst thing to happen to anyone ever.
I have never understood the need to rank-order people's hurt. I was brought up being told that there was always someone worse off than I was, and what about the poor children or the starving babies. If anything, thinking about them just made me feel worse, and it made me feel as though my feelings didn't matter. They weren't the most terrible that had ever been felt, so I should just swallow them and be grateful.
As I see it, this couple have had bad news and were reacting to it. No more and no less. They should probably have had more sense than to react in front of a journalist, but if they were young they maybe didn't realise the implications of doing so. I really hope that this sort of conversation isn't going on anywhere that they are likely to read it, as it would just add to their distress.
