Why I'm not a fan of Facebook

My dear friend currently working in UK texted me this morning that our mutual ex-colleage and his wife is also in London. Bewildered that she actually kept in touch with him, I quickly texted back on how that happened? She then said he saw her on facebook and left a message. Hmm, have never liked facebook. Don't really care if people think I'm outdated, just because I don't have facebook. What happened to my friend is proof enough, why I don't and should never have one...
