Facebook

Why does everyone have a Facebook these days? I just found out that my grandmother, mom, dad, and little sister all have their own page. I think that is just alittle bit crazy that my grandma has her own facebook because I have always thought of it as a teenager website. My mom uses facebook ALL the time and seems to everything everyone is doing on facebook. This scares me just enough to where I don't post anything anymore because I know my mom will be reading it.
