She was f’d in the head the last time I thought about her (maybe 15 years ago, if not longer), and I see that nothing has changed.
...and, yes, the shaved head was my first tip-off. I cannot think of a good reason why a woman - especially a young woman - would shave her head short of having cancer or some scalp disease. Ditto for guys...though we have an additional allowance for losing stupid bets (nope, never happened to me).
The reason you forgot to mention was if she became a masochistic submissive to an sadistic Master and dropped deep into the BDSM lifestyle.
