I have a co-worker that I’m of the opinion has some issues (don’t we all). The first thing they ever told me was one of their children had died of cancer. I’m sorry for your loss, but what? This is not an ice breaker topic when you first meet someone. Yes you might discuss your children, but not the dead ones, at least not until you get to know the person better. I kind of remember from my psych 101 class that this is a major red flag. They seem like a nice person, but boy I hope their getting grief counseling.
