That's tough. My wife and I had a similar exchange, sprouting off from a duscussion of how difficult the year has been and what we've got to deal with. Awkward.

It is maddening to hear bystanders, however well-meaning, talk about how upset they were by witnessing your car crash. But.... people are allowed to be human and their feelings are valid. Spouses who got this news as a surprise naturally have their own issues to work out. You can just hope people phrase their feelings appropriately and not in a triggering or minimizing way. And if they do you can just hope you can forgive them.
