@mayaisloading Some people may share it trying to get closer to you, in more intimate way. It’s a check if you’re ready for this kind of intimacy
Other people may expect that you share your own experience in response. It’s also a way the get closer, but in a friendly way
You’re right that you won’t share this kind of information with a stranger, so that’s why it may be important for people who want to become “not just a stranger” to you
