Find out How Well Two Person Know Each Other on Facebook.
So you’re curious to know if there are already two people you know on Facebook; know each other. And do you even want to know what kind of relationship they have? They are close friends or just acquaintances.
Of course, there is no 100% solution to this, but there is one simple trick that will give you a lot more information about any two people’s relationship on Facebook.
If you want to know if two people already know each other or if they want to explore their relationship, copy the following URL and replace username1 and username2 with their Facebook names.
This link will take you to a page with a list of their mutual friends, photos and events that they both shared together. The good news is that these people don’t have to be on your friend list. You can check the relationship between any two people if you need their username.
If you scroll down, you will see the years appear on the left side of the screen. Clicking on them will provide
accurate information that is publicly available for that particular year; for example, wall post, life events, birthday wishes, etc. So using these statistics, you can guess what kind of relationship they have, which would be difficult otherwise.
