glare in the cockpit was harsh. The cockpit ceiling was transparent for maximum viewing pleasure. âShe got Alzheimerâs disease. Do you know what that is?â
âUmm ... isnât that when you lose your memory and stuff?â
âYeah, essentially thatâs it. You forget thingsânormal things like birthdays and where your car keys areâbut you also forget how your body works, and what you need to do when youâre hungry, or have a full bladder, and things like that. The worst thing is that you forget much deeper things, like who the people around you are. So, even though she loved them so much, Ray couldnât recognise her daughters at the end, even when they were right in front of her.â
âWhat do you mean?â
âWell, she knew they were important people in her life, but she couldnât remember whether they were her sisters or her daughters, she couldnât remember their names, or what they liked to do, or if they had any children of their own, or any of those sorts of things.â
Spencer imagined his mum not knowing who he was and felt alarmed. âThatâs horrible.â
âYeah, I know. Itâs distressing, isnât it. Sorry, mate, I didnât want to upset you, but I just thought I should explain why a cloud passed over Reg back there.â
âYeah, no, Iâm glad I know. Thanks, Dad.â Spencer paused. âIs she still alive?â
âNo. She died last year, and it was a relief to everyone,if you know what I mean. Not that they wanted her to go, but just that her life had lost so much quality. The things that had been so meaningful to Ray had become completely meaningless, and just painful. So it was very hard on Reg and the kids.â
Spencer thought about Leonâs mum, who seemed to be always losing her keys and locking herself out of the house, and how, even though she had spare keys hidden in a few places outside their house, she could never remember where they were when she needed them. Leon would get a text message from his mum asking him to go home to let her in.
Uneven green lumps were now in the distanceâthe Stirlings. Dad led the Drifter into wide thermals, leaving one and picking up the next, circling towards the ranges.
âYou know how weâre going round and round and round in the same direction in these thermals, Dad. In a spiral.â
âMmhmm; thatâs how they work. The hot air rises like a corkscrew to the top, and we piggyback it, if you like.â
âBut, do you ever get dizzy? I mean, after a while in the same thermal?â
Dad laughed. âI know what you mean, Spence, butthe radius of most thermals means that you donât get dizzy. Weâre turning fairly gently, in the scheme of things.â
Spencer nodded. He took a breath. âDad?â
âMmm?â
âCould Leonâs mum have Alzheimerâs disease?â
Dad looked across at him and took a moment to answer. âUsually itâs an older personâs illness, Spence, so itâd be quite unusual for someone as young as Mrs Wilkes to have it. Why, whatâs she doing?â
Spencer explained about the keys but Dad said sheâd have to be doing loads more weird stuff for it to be Alzheimerâs. âIf she got lost on her way home from work, or went to the shops and then didnât know why she was there, or anything like that, then youâd have cause for concern, but not otherwise. Just sounds like sheâs a busy woman, and maybe a bit of a scatterbrainâbut thatâs okay. A lot of us are like that!â
Spencer was relievedâespecially for Leon. Imagine having a sick parent at this age, having to look after themâtake them to the loo and stuff. Hardcore.
Spencer leaned back into his seat and started to look for bits of the landscape that he might be able to recognise from their last trip to the ranges.
The wind shifted and raised them and they felt
