It may or may not be. It could be just a rude person who has no sense of boundaries.
If this person was a handler, it depends on if I was conscious of their behaviors. Let's say, it's a family member (which I deal with on a regular basis). I have become very bold and straightforward with them. He knows that I'm aware... and he isn't willing to come to freedom.
Sis, it has been 14 yrs for me of actively deprogramming. Sixteen years ago, I wouldn't have considered such a thing. But I have always been vocal when someone is persistently invading my space and being rude. That's just part of my makeup, I think. My sister was more passive, where I'd jump in and fight back. That doesn't make me better. I'm just expressing how I'd feel like reacting and possibly act on it.
Example: When I was 11yrs old in 6th grade, there was this huge guy who was about 14 yrs old. He was a good 10 inches taller and twice my weight. He would see me in the hallway between classes and hit me. And I was a small girl. Well, after a little bit of that, I hauled off and punched him. He never hit me again. LOL
It's just how I'm wired, sis. There's other areas where I could learn to be more assertive. It doesn't make someone faulty who isn't assertive... not by any means.
