Major Disaster

Discussing intervals with a 10-yr-old.  We'd talked 'perfect'.  Now for major and minor.

Me: So, if we forget this is music, what's major?  Like, a major ... disaster [the recent events of our country at the forefront of my mind].
Girl [quite seriously]: Bad.  Really bad.
Me: What if it was... um... they're all negative examples in my head... Okay.  What about a minor problem?  What would that be?
Girl: Not good.  But small.
Me [relieved]: Yes.  Minor is small, major is big.
