Should I unfriend my dad and block him in Facebook?

[Readingismyfave!!28]

Ok this week, my dad has been sending me messages on Facebook. I always deleted them and just lied to him when he asked if I got it or not. I changed my private settings that my dad would not see my posts on Facebook. I really want to delete him and block him, but how can I do it when he won't know? Should I lie and say: I deleted my Facebook?
I have my friends from high school, camp, college, my old high school teachers, and a few of my cousins on my "Facebook friends" just that. My dad is not a "friend" to me, he's more of a parent and I'm not crazy for us being friends on Facebook

Yea will he really disown you for blocking him on Facebook?

If he's pestering you just make a second account.

But what has he done wrong? why do you want to delete him?

I dont know what your issue is. What is so wrong having your dad on your friends list on Facebook? Thats so ignorant of you!! Lots of people have their parents on their friends list on Facebook. What is your problem? If you really love your dad you would be proud to show him off to the other people on your friends list. One day your dad will be dead and your going to wish he was still alive for you to accept a friend request from your dad. Shame on you!!!

Same situation also, i would say block him and then say you forgot your password or username. And if there's someone you think your dad would ask to see if you still where posting things I'd say block them too.
