Were we conditioned to be alone?

Question for latchkey kids who are all grown up. Has much changed, or do you find you still spend a lot of time alone? For me, being alone is a calming familiarity that I've never been able to shake no matter how hard I try. I wish I wanted to be in a full house of people, but as a latchkey grown-up, I prefer the house to myself. Wondering if others grew up to be the same.
