I'm not sure about a need for "flawless truth" but after being immersed in code for hours I do have trouble socializing and being on a less intense level with people. I find I'm inclined to be more introverted unless I've had time to unwind, or to want to discuss topics with more detail, stuff that's better discussed one-on-one than in groups.

But the same can be true if I'm deep into writing a new song as well, so maybe it's a problem moving from the specific to the general without time to switch modes?
