I recently found on Facebook the girl who I was best mates with at college for 2 years and she accepted me as a friend. I noticed today she's no longer on my friend list, but she's still on Facebook so I'm guessing she's deleted me. I wrote a message on her "wall" and she never replyed back. I feel like emailing her and asking her why she couldn't at least be polite enough to say hello. I mean I know life moves on but....how rude!
