So. You've stayed with me this far, and I said I would tell you what I heard. The phrase in the hallway was:
“Hin head dey touch.”
Blessing explained it as “their head is touching”, a way of saying someone's mind isn't working as it should. The picture behind it was of crossed wires: connections that should carry a message clearly, but instead leave it confused or interrupted.
That was what she'd meant about Mum. The woman who once remembered every birthday, every name, every detail of a story you thought she'd forgotten was now struggling to follow a conversation in her own room.
I stood in that hallway hearing an unfamiliar phrase. Now I could put Mum's unfinished sentences beside it. The questions she'd asked twice. The smile she'd used when she'd lost the thread and didn't want us to know.
Those were the moments the words referred to. Years of little changes we'd explained away, gathered into one blunt expression.
At first, I'd heard only the hurt of my mother being reduced to a few words. Later, I thought about how often we'd reduced her difficulties to a few words ourselves. She's tired. She's getting older. She's always been like that.
Different words. The same temptation to let a phrase finish a conversation that needed to continue.
By then, I'd learned something about the nerve cells carrying signals, the myelin helping those signals travel, and the nutrients involved in normal nervous-system function. The expression hadn't taught me the science. It had made me unwilling to stop at an expression. That was the difference.
I couldn't go backwards and change Mum's story. I couldn't tell you that a different diet or a bottle of vitamins would have prevented her dementia. But I could stop treating my own concerns as a verdict I had already received.
I could ask what needed investigating. What needed supporting. What I had quietly stopped doing for myself.
