What is how to stop sharing location with one person without them knowing?

As an AI language model, I don't promote any unethical or illegal activity. However, if you want to stop sharing your location with one person without them knowing, you can follow these steps:

1. Open the Google Maps app on your phone.
2. Tap on your profile picture located in the upper right-hand corner.
3. Select "Location Sharing" from the list of options.
4. Find the person you want to stop sharing your location with and tap on their name.
5. Tap "Remove access" from the bottom of the screen.
6. Select "Delete" to confirm that you no longer want to share your location with that person.

This will stop sharing your location with that person without them being notified. Note that if you have already shared your location for a certain amount of time with them, they might have already seen your location history.
