How to Accept a Friend Request on Facebook
When you receive a new friend request from Facebook, a little red flag appears over the Friends icon in the big blue bar on top of each page. You may also be notified in your e-mail or on your phone. The number in the red flag indicates how many Friend Requests are waiting for you.
Clicking this icon opens the Friend Requests menu.
To accept the Friend Request, click the Confirm button. You now have a friend. To reject the request, click Not Now.
When you click Not Now, Facebook may ask you whether you know that person outside of Facebook. In other words, is this a Friend Request from someone you know or someone you don’t know?
If you click No — meaning, I have no idea who this person is — Facebook prevents that person from friending you again in the future. If you click Yes, meaning Yes, I know this person but I’m not sure I want him looking at my stuff, Facebook hides the request. In other words, you can go back to it in the future and confirm it at that time.
To get back to hidden Friend Requests, open the Friend Request menu and click See All at the bottom of the menu. This takes you to a page where all your outstanding requests (including hidden ones) appear. You can then confirm or permanently delete a request.
You can also access hidden requests by going to the Timeline of the person who sent the request. There, the Add Friend button is replaced with a button to accept the Friend Request. Click the button to become official Facebook friends.
Some people worry about clicking that Not Now button. If you’re not sure what you want to do, you can always leave the request untouched. But never hesitate to click Not Now for someone you really just don’t want to be friends with. Facebook won’t notify her that you ignored her request.
