. I mean I couldn't tell you why any SLi would but I can tell you why I would and why I think it makes me SLI.
I let people feel my presence because when people invade my space/time/boundaries unwelcome I feel like it affects my internal comfort. I have been verbally and physically abused with my father along with bullying until I was 16~ at school. So I learned to use my presence to keep people from trying to engage me if I feel like they would affect my comfort negatively.
I find myself more so weaving through the situation to get the desired outcome I want from it, rather than overtly controlling it.
My goal is to be fit and lean. I usually do suck up my food cravings for it, but I fall victim to it other times. I can't imagine all SLI just don't give a shit about goals? I'm sure there's SLI weightlifters out there who understand the importance of sacrificing cravings and feelings in order to reach a goal in the field.
The deflection of jokes and stern remarks is because I personally feel better when I'm not in conflict with others. I wouldn't care to tell someone to fuck off, but it affects my internal comfort because now I might have an enemy to worry about in the vicinity, as opposed to deflecting it with a joke or a stern statement, I feel more at peace with how the interaction went. I also might feel bad later depending on how much rage and force I let out with the direct statement if it's not said jokingly or lightish.
