Hmm... well I only have one parent right now. My dad passed away right after I graduated from high school. Most of the last semester, he was sick, and he wasn't able to make the graduation. It was hard time for my family, because my dad was getting old and he would forget who I was and stuff, and near the end he couldn't even breathe without the help of machines. I used to argue with him (I was a teenage girl after all), but one day he was gone, and I realized how amazing my dad really was.
Anyway, I'm guessing from the way the poll is set up that having "discussions" is a bad thing? I mean my mom and I discuss things, but it's not like it's a bad thing. We just talk. We do have arguments from time to time, but that's just normal. My mom doesn't understand me all the time, but she still loves me no matter what. I think that's what makes parents special.
