When i think back on it, yes they definitely did that. I'm the oldest out of 4, 2 boys and my sister. Due to me being the oldest girl, i've always been given more responsibility, whether in good or bad situations. My parents were a lot more strict with me than my other siblings. As there is a 9 year gap between us, i was the only child doing chores while i was still living at home.
I should add that my two brothers have autism (mild).
