Precautions while using Facebook
Be careful not to provide too much information
Facebook is intended to be a social network. However, you do not need to go into every detail about your wisdom tooth being pulled or how your latest hot date ended. People do like details but only in an appropriate environment. If you feel the need to share then do it in person or over the phone. This also includes your family and friends. You may feel the need to speak about your friends latest date or their ongoing medical treatment but they may not want this information known to the world. They may have gone at great lengths to keep their medical treatment private and there is nothing worse than a non family member knowing more than the immediate family members. Respect their privacy and you will be better for it.
