It seems your parents are a lot like mine. My father actually accepted my apostasy where as my mother still has a hard time accepting it. My sister just denies it, and won't admit that I'm an apostate. She keeps saying it's a "phase."
I was very surprised when I told my father, that he didn't get mad. My sister found out first that I was a Murtad and she told my dad hoping my dad could turn things around. To her disappointment, my dad told her he was glad I acquired my own perspective of life, instead of following traditions.
My mother on the other hand seems to like the idea that I'm possessed by Satan. Whatever helps her sleep at night I suppose.
