I'm an engineer, but have had a similar observation with my wife.

I am constantly tweaking and fixing things that bug me in our relatively new-to-us house. The feedback is usually along the lines of "I never realized how annoying that was, but this is better". She has a strange-to-me ability to just not register the little annoyances.

Her approach is probably a better way to go through life, but I'm just not wired that way.
