Demanding and irritating friends?

Tell them you have better things to do than to be on F/B 24/7! Don't let it annoy you. You are not obligated to explain the reasons why you don't go on F/B as often as they do. If you don't like what someone has written on your page, delete it. They'll get the hint on your likes and dislikes as far as the messages they leave you. Some friends are just higher maintenance than others.
