Guarding Castle In The Sands

It's so hard to make, harder still to maintain So easily it can break, may never be built again! For heaven's sake hold onto it The slightest crack can rip it apart. A thing once so dear, a thing once so sweet Can go astray and break your heart. Just one hurting word, the smallest frown A little loss of patience to understand, Like a card house it comes crashing down, With one unguarded blow of your hand! Be careful, the castle is built in the sands, There's dark cloud, gale and thunder Hold onto it with your heart and your hands Let it not for heaven's sake come asunder.
