how does facebook work?

[Brent]

If someone requests to be your friend, and you accept, do you have to do the same back - or do you automatically become their friend and are on their friends list?
Thanks.

[Anytha]

you two automatically become friends

If someone sends you a friend request and when you confirm his request, you will be his friend and he will be your friend and both of you can see each other in their friends list.....
you automatically become their friend and are on their friends list.......
if you delete the friend request, both of you cannot see each other on their friends lists...!!

If someone request you and you accept the request means you both automatically will be friends and Viceversa.

No, you don't need to do the same back, once you accept the person's friend request then you are both automatically friends.
