I have had a Facebook since my senior year of high school (2011), then got rid of it for 6 months when I was a sophomore in college (2013). Neither before, during my break from it, nor after now, have I ever thought Facebook controlled me in any way. I simply use it as a tool for staying in touch with people. I have people living in a few states that I simply cannot go and visit right now, but finding an easy way for us to talk (I have one bar of cell service at home) makes staying in touch easier. I don't read my news feed that my much or anything like that, but I use the site just as another tool like my
PAPER address book for keeping in touch with people.
