My wife is a pet sitter and pet sitting can actually be quite dangerous. She once got bit by a dog and called me to come and help. She was in too much shock to be able to explain where she was, and I'm absolutely terrible with directions so I was unable to locate her.

Thankfully, she managed to calm down and resolve the situation as it was only a small bite, but if the situation was worse and I would have been too late to find her. We thought that we can't let this situation happen again, so we now share each other's location just in case anything like that happens again.

It's also great knowing how far away she is so I can start dinner and have it ready for when she steps in the door.
