Preference of subjects

[mycrabface]

Okay let's say that this guy likes maths, maths and maths, so he's considered kinda like a logical person and thinks logically. And then let's say that this girl likes art and literature stuff, so they think and do things differently.

So let's say they marry.

Are they more prone to quarrels and fights than other couples who prefer the same subjects?

Because if you create a situation:
guy says: why'd you have to choose different coloured placemats? And can't they at least be the same size?
girl says: I just like them that way okay, so its not too boring like everything else in this HOUSE. Everything's so MUNDANE. I CAN'T LIVE LIKE THIS D*MMIT.

So they could be quarrelling over such things. These problem are caused by their preferences and which side their brain functions mostly from (I hope you get what I'm trying to ask) which decides what subjects they like.

Btw I feel like a saint today: its not how you avoid quarrels, its how you get through them.
