I use Facebook to keep in touch with friends and family that live in other areas of the country. My niece was posting some crazy stuff a year ago and I actually thought about unfriending her because I was tired of seeing all the stuff she kept posting, then I thought that she didn't need people to drop her, instead she needed support from her friends and family. I kept her and helped her through a tough peiod in her life and I am happy that I did.
