A good friend of mine organized an unexpected birthday celebration for me, it was very sweet of her to do that for me.
You must be a very special person to her. Is she single? 
She is actually in a long term relationship. She is a considerate person though, which is cool.
Too bad, oh well, if things turn around in her status, you have someone in her that you can consider
It's good to have true friendships, always nice to depend on others when you need them.
