whats the definition of a parent?

what is a real parent? someone who give birth to you? someone who only hits you up on holidays or birthdays if even that? someone who promises you things time after time but none of it ever happens? someone who post stuff on the internet because your doing so great and they want to take credit as being your parent like they were there? i really don't understand what a PARENT is. cause the title means nothing to me. im only 18 and i do things on my own; I'm so tired of the drama, I'm so tired of the fakeness. only parent i recognize is the one in GRANDPARENT. those are the people that have actually been there, and helped me through it all. to you my name is ASHLEY. not daughter. not sweetie. not anything but Ashley. you didn't help me get where i am. you never called. you never gave a damn. & don't say people prevented you cause I've lived in the same house my whole life, house number has never changed, you knew what schools i went to. never made an attempt. knock it off. & i been done trying to care. i just don't care anymore. i don't want to build a relationship. & its sad when your everything. your all. your best-friend turns their back on you & disappears. a child should never feel betrayed by their parent but hey that's life huh??? its sad when your kids don't even know each other like that, having them on Facebook and knowing there name don't mean a thing. this is for my so called parent(s).
