I moved the verses around. I also changed some of the lyrics. I added some chords between verses. I added an instrumental part after the last verse and before the final arpeggios. I added a little percussion.
verse:
I should have know it wouldn't last.
You said so little about your past.
Should have wondered what you had to hide.
Should have asked what you left behind.
chorus
The southern sky makes me sad,
Missing someone I never really had.
You left me for your other life,
Your other home, your other wife.
verse:
It's Friday night and you're in some cantina.
You gave up our favorite wine for tequila.
I hope you're happy in Mexico,
Where you know I'll never go.
chorus
verse:
Scorpio points across the border,
Far away from law and order.
Can't help looking no matter how I try
I spend evenings watching the southern sky.
