If a relative is consistently odd, and has always been odd (and many of the family's comments lead me to believe this is true of Castro), then when that family member does other odd things, in my experience the typical reaction is to try to ignore it. I have plenty of family members who either do odd things or things that I consider to be detrimental to their lives, but I'm not going to bring up the elephant in the room unless I have no other option because it will create conflict. Most human beings, I imagine, are the same way. I am not at all surprised that Castro's family did not bring up his bizarre behavior. It undoubtedly seemed the much easier option, and most people prefer the easier option. Most of the time, when we ignore our loved one's odd behaviors, it does not lead to such a horrific scenario.
