I've been scrolling (on mobile) while watching at people's dens for sales or just because I think they have a pretty den, and more than once I've been accidentally sent friend requests to people. I wish I could cancel the friend request but apparently you can't... so I awkwardly have to message said person to cancel the friend request.
It's quite an embarassing and stressful situation that could be easily be avoided by letting users cancel the pending friend requests without them needing to invade user's dms over this stupid situation...
