As others have said, you need to sort out your security settings. I have everything on 'friends only' so only my friends can see anything I post. I do have 'friends of friends' so people can ask to be a friend of mine simply because then friends/family members who are not already a friend scan ask me to be a Facebook friend. I did have friend requests set on public for a while, but then I got a friendship request from someone in India!! So I changed the setting. However those friend suggestions are just suggestions, you don't need to worry about them because they can't see your page (unless it's public setting). Just change your security settings, don't put anything on public, and it'll be fine. I like Facebook because it keeps me in touch with people in my wider family and more distant friends, and old colleagues, and even a few people I was at college with so long ago. I never post or 'like' anything political as I have Facebook friends from every political view, and I don't want to cause any upset or offence. I just keep to little bits of news, or a few photos. Enjoy Facebook, it's just a tool for keeping in touch with distant friends.
