Yeah, this is pretty funny. I'm sure many people get drunk or lost on a night out and spend the night sleeping rough so this isn't exceptional at all. In fact, I have no idea why she even told people she drank her own milk. Imagine admitting to drinking your own piss after spending one night out in the wild. I'd just keep it to myself out of embarrassment. If I was out there a week it would be a different matter, but a day? This shouldn't be news at all other than how stupid she is.
Do you not drink cow's milk? I think that is far more weird drinking the milk of a beast.
