Men are simple compared to women ... the song "Mood Ring" written by Paul Thorn pretty much sums up one aspect.
I know nothing about this woman, Everything I do is wrong
Sometimes it's hard to fathom, Just what page she's on
I found a pretty little mood ring, At the local five and dime
It's gonna' solve all my problems, For a dollar ninety-nine
I followed the instructions, I read them word for word
I memorized the color chart, Cause I wanted to be sure
I told her, "Baby it's the thought that counts", When I slipped it on her hand
And then I crossed my fingers, With this ring I'll understand
If it turns black, I should turn back
If it turns red, She liked what I said
If it turns blue, I should leave her alone
If it turns green, She wants me I know
