I can't believe it!

So, some of you know that my "best friend" Jean totally blew off my 50th birthday last year and I still am bitter about it. I made a huge deal of her 50th birthday with many cards and a nice gift that I mailed to her. Her excuse was that they had moved...OK, whatever. It was very hurtful and I eventually did tell her. Guess what? No card, e card or any mention of my 51st birthday. What is up with her? I'm just not important enough for her to pay any attention to, I guess. This friendship is a habit that I need to break.
