I was about to leave my office when my messenger notified me a message. One of my old colleague knocked me. I was surprised and happy at the same moment. She was vanished from our group and we don't have any clues about her. She deactivated her account, switched off her number and pufff.... Gone. But today she knocked me from her account. We had a long chat but I never asked why she disappeared from us. She didn’t tell either. But at the last moment, she felt that it was I who really cared about her as all our friends didn’t want to talk with her as they showed attitude. That's rude, isn’t it?
