conv: I visited an underground cavern that was like 23 stories beneath the surface_comma_ i was uneasy to say the least.  I recently went to ruby falls_comma_ an underground cavern with a waterfall.  That sounds awesome. Have you ever been before? Not that particular one_comma_ no. I had butterflies in my stomach on that elevator going down 23 stories. I wish I could go sometime that sounds like quite the experience. Overall it was a good time_comma_ but i was nervous being that far underground_comma_ i need to learn to relax and enjoy things.
