No tides

Why cant oceans just flow, like a gentle river stream    
Is it just me, thinking out loud, during a long and vivid dream    
Instead of crashing into shore, then going back for some more    
Just trickle towards the edge, without a noisy, almighty roar    
Ships and boats, would never ever be, tipped and sunk    
Girls on the shore, would never ever see, a ripped surfy hunk    
No whitecaps to see, no tides to ruin sand castles on shore    
Precious marine life just swimming and crawling about    
Not getting tossed all about, they’d be happy, that’s for sure    
But for this to work, its way to challenging    
For we still rely on our orbiting moon, to be happening    
That’s what my dream didn’t quite bother, to fully figure out.
