Is my privacy settings on facebook not working?

[thomas.banks@rocketmail.com]

I have made it so my family on facebook cannot see the wall posts I make, however I still get daily questions from my mother asking who someone is, what something means, why did I say that, etc..

I thought this was supposed to be out of her view after the settings that I made. Are the posts that I make still visible to EVERYONE if they go on my profile, regardless of settings?

I just don't like these awkward questions, family on facebook shouldn't have mixed.
