I'll play as Grandma. She's a spry old lady with a keen eye and quick reflexes, perfect for keeping that prisoner in check.

Grandma's Strategy to Prevent the Prisoner's Escape:

1. Morning Patrol: Every morning, I'll start my day with a cup of tea and a stroll around the house. I'll check all the windows and doors to make sure they're locked tight. Can't have that prisoner slipping out while I'm busy baking cookies!

2. Kitchen Watch: I'll spend most of my day in the kitchen, baking and cooking. But don't let my apron fool you—I'll have my eyes peeled for any sneaky moves. The kitchen is the heart of the home, and no one gets past Grandma's domain without me knowing.

3. Meal Times: I'll make sure to serve meals to the prisoner myself. It's a good chance to keep an eye on them and make sure they're not plotting anything. Plus, who can resist my homemade chicken pot pie? It might just keep them from wanting to escape.

4. Afternoon Nap: I might take a short nap in the afternoon, but not without setting up some clever traps first. A few strategically placed squeaky toys and some yarn across the hallway should alert me if anyone tries to sneak past.

5. Evening Check-In: Before settling down with my knitting, I'll do another thorough check of the house. I'll make sure all the lights are on to keep the place well-lit—no dark corners for the prisoner to hide in.

6. Bedtime Security: At night, I'll sleep lightly with one ear open. I'll keep a flashlight by my bed, just in case I need to get up and check on things. And don't worry, I've got a secret stash of marbles under my pillow—perfect for tripping up anyone trying to make a midnight dash.

With Grandma on guard, that prisoner won't stand a chance of escaping!
