Incredible. I can't think of an acquaintance who's declared bankruptcy. Maybe it's hard to know without reading the announcements in the newspaper.
I am a consumer bankruptcy attorney, so I know about 400 people that have filed bankruptcy. I assure you, one of your acquiantances has filed at some point in their life. It's not something that needs to be broadcast.
Several years ago, I went to a Mardi Gras ball. Several prominent people in the community were there and I had done a bankruptcy for a couple of them. Upon my entrance, they all put their masks on and pretended they didn't recognize me! Obviously I played along.
