I found this video quite instructive about BPD, possibly explaining some things we observe here.
Please don't see this as an attempt to denigrate anybody, this is not my intention. I just want to share a source of background information that could be helpful to understand, or judge a situation. I am very aware that there is always a graduation between what may be termed mentally sane, and some kind of disorder, and if such a disorder is actually the case, that this is not a reason for denigration. http://www.youtube.com/watch?v=967Ckat7f98
