Friending someone on Facebook, and occasionally liking their posts, is not in and of itself how you make and maintain a friendship. I am not saying technology is bad, it just can't take the place of being in the moment and having real human interaction. I know we cannot always be together, e-mail is nice but nothing says "you matter" as much as a letter sent through the mail, or a phone call or better yet a lunch together.
My second resolution is to make more time for friends, in the real world. More face time, less Facebook time.
