Not only does clicking the See Friendship tool let users view photos, comments and events shared between themselves and their friend, it also offers a search tool to do the same between any two mutual friends, making it easy to see everything any two people have ever said to each other Facebook. As usual, the site should have tested the function out on their users first, with one saying: 'I've always wanted this! And yes, I'm a creepy stalker.' Also, as usual for Facebook, all users are automatically opted in, and there's currently no obvious way to turn it off."
