I like text messages. They are excellent for sending information/ quick messages or just to say hey, I'm on my way home or whatever. Quick and easy but if you are talking about long conversations, I'd rather talk on the phone.
When you block a person, they can no longer invite you to a private message or post to your profile wall. Replies and comments they make will be collapsed/hidden by default. Finally, you'll never receive email notifications about content they create or likes they designate for your content.
Note: if you proceed, you will no longer be following .
