Why dont people accept people they KNOW on facebook?

[BelovedAssassin715]

My friends brother ignors my friend request, and I know its just facebook but it makes me feel when someone wont add me, like I've done something I don't know about to make them mad. Is it probably just because i'm not good friends with him?
But then if he doesn't like me, i don't know what I've done or how I've made him not like me, when we hardly talk in real life. I talk to his sister, and babysit his other sister, and that it.

idk, but I've added a lot of people from my school that I know and they ignored my friend request, but I just block them when they do that.

i'm not too sure in your case, maybe he just doesn't check his friends requests because he got so much spam friend requests... maybe he doesn't want you to know about some of the stuff on there...
i have a friends who don't add people they know because, they "know" they'll b*tch about her behind her back... she doesn't add her own sister because it theres pictures of her smoking and she doesnt want her parents to know...
i think you should just up to him and say "add me"... but otherwise dont take it so personally
edit: i just saw you say you hardly talk in real life... so why does it matter to you so much?

No.he might be a good friend to you in real life.but i think he has personal stuff on facebook that he doesn't like you see them.
