Kids, why did I want them?

Sometimes I have a feeling that feels like

Why did I want kids?!


Even when I'm feeling a sick, they really don't think 'Let's be nice to each other'. No they ar still arguing about the littlest things.
They are nice to me and ask if the can do something for me, but when my daughter askes something to my son.... He's like 'No, I'm not doing that!'
and afcource is he askes something to her it's the same.

I'm asking them why they can't be nice to each other.

They have to much answers and talk through each other, almost shouting..
I think again, why did I want...
