An SLI I know recently told me about how her neighbor has recently withdrawn from interaction. In the past, the SLI and her neighbor have been on fairly close terms. But suddenly, over the winter, things changed. And while there are some strange things that the other person did, I find the SLI is not exactly trying to improve things. It's a bit like she sees the situation as a green light to be more openly hostile to the person or to push the neighbor's buttons even more. What's more, I know the neighbor has been having a lot of stresses in her life (husband recently died, getting older, etc), so I can suspect a lot of reasons for things to be getting weird.
I bring this up because I saw this within myself, as well. It wasn't until after a lot of schooling from delta NFs did I really start to consider how much I was making things worse by doing things like that. I'm surely not perfect now, but I understand it a bit more.
As such, I was trying to explain to the SLI about how the sudden change probably is related to some other issues in the persons life; that some of the pettiness from the other person is probably not going to be aided by retorts that are specifically designed to cause damage.
It is strange, because I know the feeling the SLI has in regard to the said person. But I also appreciate the NFs for dealing with and hopefully helping out the STs; I wish the SLI had an IEE in her life . . .
