I miss having hair
Same. I nearly never wore the pony and only just noticed it after posting this pic. It was peak Nirvana days (and I saw them later that year in Dublin or maybe the next year) and we called that hairstyle an "undercut". Here's a pic from the same trip where it was my usual. I am pretty sure this is on the overnight train from Moscow to St. Petersburg.
What a great twist. I've had solid success with ChatGPT for stuff like that in the past so put your description in and it couldn't come up with anything.
It did give some useful information which I can paste in here if you don't have an account?
Mostly it was asking if you could remember any other detail like character names, setting or even tone of the writing.
