Lyrics I Don't Understand: Sometimes When We Touch

And sometimes when we touch
The honesty's too much
And I have to close my eyes and hide...
--Dan Hill

• Can someone please explain what it means when the honesty's too much? Too much what? Also, why must he hide? I don't get it. 
• Does anyone have a copy of the cliff's notes for this?
• Please help me. This makes me crazy. 
• Do I just not get love in the 70's?
• Am I missing some sort of passion/complexity gene?
• Are my relationships just not meaningful enough?

Perhaps, I'm over thinking this.
