Yeah, she can be pretty rough, but she does have a good reason. She got into this relationship with Goku only knowing that he was a very skilled fighter. Then things turned for the worse when Raditz came. Things started getting weirder and weirder. I'd be pretty mad too. And I think she rants so much because it seems all the boys think they can just do whatever they want because they're strong and saved the world a bunch of times. She still deserves some respect and inclusion in what her boys are doing. That's a mother and a wife deserves.
I do agree with you though. There's been some times when she would rather have Gohan do his homework than let him give the needed help to save the world

You're very welcome!! X3
