Another time I'd been physically hurt the night before I was to have a meeting with a business associate. I had difficulty walking without it showing that I was in pain, so already here I had to set aside some feelings, overriding the Neural Signals that told my brain I was in pain. Pain is a condition that can be quite compelling in terms of hindering normal movement, but moreover, I was hurt in a way that left me no choice either way because a muscle in one of my arms had been partially cut through and therefore couldn't function normally. I'd probably been able to set aside my discomfort from the pain, but the physical inability to control my movement was unsettling.
Obviously I didn't exactly look forward to show up in a weakened state, and I certainly did not want to wince in front of my associate while we were negotiating a business deal. As mentioned, the latter I might've controlled but not the former, and so this is a good example of a situation where I definitely had to set aside feelings both physically and psychologically.
I have to say that my Reader is right: We (psychopaths) do have the ability to put our emotions aside, though how easy it is differs quite a lot individuals in between, and it also differs what types of emotions we can easily put aside though there are certain commonalities. Frustration, f.x., is I feeling I cannot always easily put aside even when it would more than suit me, and the same is the case when I get very angry.
There is another type of situations where setting aside feelings can get into play, namely in a Buridan's Ass kind of situation where you're torn between two different possible lines of actions and both are equally appealing or vice versa. One such situation could be if you get to like somebody but for some reason have to either leave and save yourself some trouble or stay and suffer the consequences, and the other person would prefer that you stay. The catch usually is that the consequences you may suffer will also affect the other person, so the best choice will often be to leave. Or you might save the other person some discomfort by leaving but you really want to stay, and then it's a matter of weighing for and against: Will my discomfort be so severe that I think it'll be better to let the other person take some unpleasantness, or will it in reality be a minor discomfort to me and worth the satisfaction of knowing the other person didn't get hurt? I've had both types of situations.
The funny thing about it is that I still don't remember having to set aside any of my feelings or emotions, I see it more as a choice between which feelings or emotions I would engage with. This is a particular trait in psychopathy termed as 'fleeting emotions' and is related to 'Shallow Emotions' and 'Shallow Affect' or 'Flat Affect'. It still confirms nicely what the Reader said just as it does what I wrote in my previous article (mentioned in the beginning of this text).
I hope with the examples on this page to have given some idea about what types of situations that the Reader's statement have relevance for and to thereby also exemplify what the difference is between situations where you (if you're a psychopath) have no emotions to detach from in the first place and situations where you do have to make a choice and sometimes decide to not engage certain feelings.
Lastly I hope to not disappoint by not presenting better examples. It is not ill will, I just don't have any examples where deciding to detach has been either more difficult or relevant to me than the ones I have included in the descriptions above.
