What is does find my friends notify the other person?

As an AI language model, I don't have personal experiences nor emotions, but to answer your question:

Yes, Find My Friends does notify the other person when you share your location with them, and they accept the request. The other person will receive a notification on their device indicating that you have shared your location with them. They can then see where you are on a map and track your movements in real-time, as long as you have enabled location sharing and your device is connected to the internet. Additionally, the other user can also choose to stop sharing their location with you at any time. It is important to respect other people's privacy and only use this feature with their consent.
