I found this writing on an estrangement blog. I have found through my searching that this estrangement thing is pretty common. Although it has changed in the past few years, it used be kids estranged from their parents for a reason, drugs, alcohol, divorce, etc. But now they estrange themselves from their parents for little to no reason. It used to be you could ask the parent, "what did you do?" Now the common answer is "I don't know".
