What about all the people you asked to be your friend who ignored or deleted your request?
Facebook keeps track of that To see all these people:
1. At the top of the Facebook page click the Friend Requests icon (two people in silhouette). You’ll
see a list of suggested: “People You May Know.”
2. At the bottom, click the “See All” link.
3. On the next page, under New Friend Requests (assuming you don’t have any) click “View Sent
Requests.” Then you get a list of the people who hate you. Or maybe they just don’t check Facebook
that much. Probably both. Hope is quite simple!
