Respect has to be earned. It's not a 'given'.
Though I appreciate my parents for not aborting me (I was an unplanned pregnancy while my parents were merely boyfriend and girlfriend) and paying the cash for a large amount of my existence, my childhood experiences prevent me from feeling too much warmth towards them.
My father, especially, treats me as some kind of disgusting mistake he made and probably wonders how his sperm could have a half share in something so awful. My mother just prefers to think that everything bad that happened to me is the fault of my 'problems' and especially me, rather than anything to do with her.
