Back to the baby laugh.......ALL laughter is wonderful, some just better than others.  Hubby has an amazing contagious laugh.  Once at a restaurant, the owner came out and asked if she could tape his laugh to play when her employees were having a bad day.....lol.  
  Yes indeed.....water is a great sound.  Whether it's lapping against a boat or trickling down a fountain or dancing on your roof,  it always has an affect.
