Against my better judgment, I will attempt to answer.
My mom died when I was 10.
Dad worked full time as a machinist.
My two older sisters had lives (college, work, boyfriends, etc).
From age 10-18 I had a tremendous amount of alone time.
Not chosen but not unwilling to adapt (weed, truancy, delinquency, opposition and defiance etc).
I was married 15 yrs, lived together for 20 yrs.
My ex spent the bulk of her free time with her parents and sister, I did not. Long story but they all were in the teaching profession and had coordinated vacations and summers off, I did not.
Again, not chosen and not unwilling to adapt (grow room, golf league, softball league, card games with the guys etc).
I realized after my divorce there was a limit to how much alone I could mentally handle.
I pamper myself every time I slip off for a bowl or two and a song through the headphones.
There is a danger in shutting off too much but through experience, you find a balance.
My dad used to say “It’s tough but I doubt this is the hill you will die on.” To me this means you chose your battles. Some solitude I will fight to preserve and other I will let go as likely too much or over the top.
I get a great deal from my work. I tend to chose jobs with great independence and accountability vs micro management. I cover a several county wide area in my state and I can sometimes be driving for 4+ hours in a day to conduct an investigation. This equates to a good deal of my solitude requirements (bluetooth good tunes through the car stereo and stop at nice scenic rest areas for "tune ups).
It’s been a whole life(style) that I adapted to, learned to appreciate then needed to temper a bit.
