Yes, all the time... It was awful, and they stayed together... I really wanted them to get divorced.
It bothered me even more, to know that they adopted me, when they had no business in doing so, since they ALWAYS fought. Seriously, they set a horrible example of marriage; cussing, throwing things, bullying each other, name-calling... They had three biological kids of their own, then adopted me, because my mom 'wanted a girl.' Sorry, that reason is simply not good enough!
Parents who think it doesn't affect their kids, are living in a dream world, and they need a rude awakening... I promise, kids don't give a rat's bum *what* the parents think is so important that it 'needs' to be argued about; they just want them to STOP! Yes, it has affected me... To this day, I want nothing more than peace and harmony.
*edit* Like others have mentioned, I get some anxiety/irritability when couples fight... When my parents come over---if they start to have even a little tiff---I warn them that they will stop, or they will leave... Honestly, I feel sorry for them. And, for myself as a child... I was robbed of a decent childhood, could never have friends over, was afraid, and pretty lonely. (And, I was always 'referee,' something a young child should NEVER have to be for their supposedly adult parents... They knew it affected me, and they continued on... I remember telling them---when I was 8---"I hope I NEVER have a marriage like yours!")
