I've been functioning on far too few hours sleep for the last few weeks, because I left my job, started up my own business, and my mother had a hip replacement in the middle of all that, so I've been looking after her.
I drove mum out of town for surgery and stayed for a week, visiting the hospital twice a day. No matter how fried she was on morphine and other drugs, no matter whether she'd just been woken up and was still spaced, she didn't screw up on pronouns, not once. I'd be there and she'd be ripped out of her mind and the nurse would be asking who would do something when she got home, she was so stoned she didn't know I was there and she said "my son will do that".
It just registered on me, through my lack of sleep, that that means my mother has finally internalized the change. She's no longer translating in her head, but she's actually got me in her brain as her son! That's pretty darn good, considering I've only been her son for a year and was her daughter for 43 years before that.
