Distraction looking like arrogance

This is something I wonder about. Doesn't an often distracted person somehow need to be extra affirmative of others? At work I'm constantly approached by coworkers and have to produce decisions for them in the middle of doing something else. I feel since I act confused and indecisive when my thoughts are interrupted, make mistakes and then change my mind that I need to be extra kind to the people who put up with it. 

ADHD people close to me are naturally even more distracted. I find I quickly lose patience with them since they don't really try to compensate for it.

Does anybody else feel it's hard to distinguish between ADHD distraction and arrogance? There's a fine line there, and most of the time I'm not sure what I'm seeing. Sadly this disrupts several close connections for me. Possibly because decades of ADD marriage have made me extra irritable to self-centered and entitled behavior. But I remember being angry with some of these people even as a child for their unawareness.

I wish I could see the difference better and also have more compassion for ADHD behavior in my loved ones. But I suck at it at this point.

Meanwhile, these relationships grow quite cold. Despite everyone involved wishing it were different. It's sad, but I don't know what to do about it. It's also mostly up to me to initiate any change, as usual. And we need each other.
