@celia16 That sounds exhausting and frustrating. I'm so sorry you're having to deal with that. My dad will open the door and walk into my office, so I hang a "do not disturb" sign when I'm in a meeting. But, if your dad is calling out to you, a sign won't help. I didn't have any good suggestions, so I asked the ChatGPT AI agent for some. You might have tried these things or are already doing them, but this is what it gave me.

Create a routine where you proactively attend to his needs at set times (e.g., bring him water, empty his wastebasket). Let him know, “I’ll check on you every hour to see what you need.”

Respond calmly but assertively to non-urgent requests: “I’ll help with that in a little while, Dad.”

Use a timer or clock to show when you’ll return to help.

Place commonly requested items (water, handkerchiefs, newspaper) within easy reach.

Use a basket or organizer for items he frequently asks for, like glasses, pens, or snacks.
