It is possibly the "drama" of the moment of being filmed..it is the "Barbara Walters or Oprah moment" when it (the reality) is retold and made more vulnerable to our own pushed down, suppressed feelings..in that moment. It is weird, the public airing of it..makes it seem more palatable. She, like I..quickly repressed and moved on...maybe it is the very telling/acknowledging of the story in this type of interpersonal setting (a documentary) vs a quick get it over with explanation, that makes it real and emotionally charged again.
