Over the last couple of years I've become caregiver to my mom who has senile dementia and can't function for long on her own. It's now nearly a 24/7 thing which means I can't get out much so facebook has helped fill the gap of human contact. Also it's put me back in touch with some people and makes it easier to stay in touch with distant family & friends as I'm not a phone person. It also enabled my two youngest sons to connect with their half brother from whom they were separated when they were small children. It's all about connecting with others while not giving out much information about yourself for strangers to latch on to.
