My 15 year old daughter and I go round and round all the time about that very same thing. I dislike being interrupted possibly more than she does. The thing is sometimes I have to communicate something to her, but she does not give an opportunity for me to butt in without interrupting her. She literally always has her headphones on. I have tried to set up specific times for us to talk- right home from shcool, right before bed, at dinner. But outside of that I still sometimes have to talk to her. She has a billion activities and I have a really hard time keeping up with her. Shes popular, in 3 different bands, and sports. I'm proud of that. I have a whole seperate schedule just with her events.
Almost all of the time the thing I need to talk to her about is for her. So I find it particularly disrespectful of her to act like an ass when I do have to ask her something, like when she puts the headphones back in before I am done saying what I have to say. How passive aggressive is that? I can be very verbose but really try to keep it to under 30 seconds. She has no concept of what its like for me to keep her events in order, drop off/pick up times, whose house shes gonna be at. As a single father its alot.
I don't think its an as/nt thing so much as a teen/parent thing. Shes the normal one and I have the aspie traits. But my priority isn't to make sure she finishes her favorite song but to keep this house running to the best of my ability. For her. Because of her. On some things she realizes the best way to get what she wants is in fascilitating me on providing it. But she still fights me on so much its not funny. I think maybe if you went a little out of your way to let your parent know that they are appreciated and ask what you can do to help communication you may very well come to a favorable compromise.
