Jeez, Xandio --
Of all the horrible things people can do to each other, especially those who situationally are supposed to be "close" to us, or to "care", I think one of the worst is indifference. Ambiguity.
It would almost be preferable if they yelled and screamed or got violent or something, than to just pretend that your pain and distress didn't exist. That YOU didn't exist.
I don't know if you're familiar with the late comedian Jonathan Winters, but he had parents like this. After he went away to war, survived, and came back, he found that his parents had given away all his possessions. When he asked why, they indifferently responded, "We didn't know if you'd be back."
I mean -- how do you HANDLE something like this?
