I don't know that I made a big issue of POSSIBLE DISGUSTING DETAILS OF THE TRIBULATION with my kids but I remember other "friends" who had an almost unhealthy fixation on it. One sis told me that she often imagined having to eat bugs and such to survive in prison. She was quite descriptive when explaining it to me. I wanted to go home and barf.
Maybe that's why she stopped bathing regularly several years later....more practice for concentration camp life in the great trib.
