What is it about me?

I'm so tired of being the "friend" that everyone forgets about. What is it about me that makes me so hard to remember, or care about? You all have your best friends that you do everything with, that you see all the time and tell all your secrets too, well did it ever occur to you that I don't have that? I have to ask to include myself in things because given the opportunity, no one will remember to ask me. What is it about me? Am I not best friend material? I give up. Maybe it's a blessing that I'm not coming back to Meredith... but I really think it's a curse.
