Hannah remembered the specialist explaining that symptoms and progression varied, that support could help Arthur maintain independence, and that the family should plan carefully around safety.

Arthur heard very little after the word Alzheimer’s.

He knew what it meant.

His older sister Margaret had lived with dementia for years before her death.

He remembered visiting her in a care home and discovering that she no longer recognised him.

He remembered bringing flowers.

She had thanked him politely and asked whether he was the gardener.

On the drive home, Arthur had pulled into a lay-by and sat there for nearly an hour.

Now he was seventy-four, holding a folder of information about a disease he had once feared from a distance.

Hannah reached for his hand.

He let her take it.

But when she asked how he felt, he said, “I’d rather go home.”

The argument about looking after Leo began that same evening.

Hannah waited until the little boy was asleep.

Arthur was sitting at the kitchen table, turning the specialist’s leaflet over without reading it.

“Dad, we need to talk about childcare.”

He looked up.

“No.”

“You don’t even know what I’m going to say.”

“I know exactly what you’re going to say.”

Hannah pulled out a chair.

“I can’t leave Leo with you for entire afternoons if we’re not sure how your memory is affecting things.”

Arthur put down the leaflet.

“He’s my grandson.”

“I know.”

“I’ve looked after him since he was born.”

“And you’ve been wonderful.”

“Then what’s the problem?”

Hannah took a breath.

“The problem is that he can run into the road in two seconds. The problem is that you forgot the cooker was on. The problem is that we need to understand what you can manage safely.”

Arthur’s jaw tightened.

“You think I’d hurt him.”

“No.”

“You think I’d let something happen.”

“I’m saying we have to be careful.”

He stood.

“I raised you alone, Hannah.”

She looked up.

“I remember.”

“I worked six days a week. I kept this house. I made sure you had everything you needed.”

“I know you did.”

“And now you’re telling me I’m not fit to watch a child for an afternoon?”

Hannah’s voice grew strained.

“I’m telling you that having raised me doesn’t mean nothing can change.”

Arthur stared at her.

She continued.

“You taught me to look both ways before crossing the road. You made me wear a helmet when I learned to cycle. You checked the locks every night.”

“What’s your point?”

“My point is that you took precautions because you loved me. That’s what I’m trying to do now.”

He looked away.

For several seconds, the only sound was the refrigerator humming.

Then he said quietly, “You’re taking him away from me.”

Hannah felt something tighten in her chest.

“No, Dad.”

“You are.”

“I’m trying to keep both of you safe.”

Arthur picked up the leaflet.

He folded it once, then again.

“Safety,” he muttered. “That’s what everyone calls it when they stop asking what you want.”

He left the room.

Hannah sat alone at the table.

She had expected the conversation to be difficult.

She hadn’t expected to feel as if she were betraying him.

The following weeks brought compromises.

Arthur would no longer be Leo’s sole caregiver for long periods. Hannah adjusted her working hours and arranged additional nursery days. When Arthur spent time with Leo, another trusted adult would be available, and the household adopted more consistent routines.

They fitted a safer cooker arrangement, organised medication, and placed a simple information card inside Arthur’s coat.

Hannah began accompanying him on unfamiliar journeys.

She also suggested that he carry a mobile phone.

Arthur regarded the device with suspicion.

“I don’t want people tracking every move I make.”

“It has an emergency contact.”

“I know my daughter’s telephone number.”

“Dad.”

He looked at her.

“Sometimes numbers are harder to remember now.”

For a moment, he seemed ready to argue.

Then he sighed.

“Fine.”

He learned to use the phone reluctantly.

But the black notebook became something else entirely.

Something private.

Something he could control.

He began filling it in earnest after the specialist appointment.

At first, he wrote facts.

Names.

Addresses.

Telephone numbers.

The days Leo attended nursery.

Which cupboard held his favourite cereal.

Then he began adding drawings.

Arthur had never been comfortable with elaborate emotional conversations. Drawing offered a way to say things without having to explain himself.

He sketched the blue swings at the park.

The red postbox outside the bakery.

A bus stop beside a stone wall.
