If there was one thing he regretted, it was that he couldn't remember what it felt like to be alone anymore. He had unwittingly traded away his solitude — or something extremely similar to it — in return for his newfound happiness.
No… Using the word "regret" was out of line, even if I was exaggerating.
I don't regret it all. Not a single bit. I've never been happier in my life. By all rights, I shouldn't even be complaining…
He just felt like something had changed. For his entire life, it'd been him against the world. He had kept his distance — kept his guard up — and done his utmost to limit his interactions with other people.
It's not like I hated people. Not in general, at least. I just couldn't bring myself to deal with them anymore.
I just found it to be a tiring exercise in futility.
