... Any time I attempted to grow my hair out, inevitably someone would have it cut off again.

[The "someone" probably isn't hard to guess. It's also said with a blase shrug, even as he goes from playing with her hair to just holding her cheek gently.]

Among the living, it's usually considered "messy" or "abnormal" for a man to have long hair - unless they're some sort of rock star, which obviously wasn't in the cards for me.
So mine was cut on a routine, even when I expressed that I wanted to try it long.
