I didn’t tell anyone either; however, the response to me leaving Facebook was different than your experience in that NOBODY noticed. Nobody texted me to ask me where I was, nobody emailed me, nobody called.
I guess I wasn’t as important as I thought I was to my Facebook friends which is a funny thing to note — here I was spending so much time on a daily basis looking for ways in which to post the perfect picture or funny update, and nobody missed me! Not one person.
