Parents mistakes

I think my parent's mistake did not have an effect on me because everybody makes there own decision. Like in our family we don't talk about the mistakes they've made we just see them. But by my parents making there mistakes i see how much it affected them and i think to myself i don't want to make the same mistakes. Like i think there mistakes don't have to haunt us because that was them and were us. And were allowed to make different mistakes not the same ones.
