Keeping the Sea at Bay

Keeping the sea at Bay : The tide was coming in at a pace at the end of the day and people were getting wet...moving there clothes and surf-boards up the beach away from the in coming tide but not these two...they were determined to stay where they were...and started to build a barrier of sand to keep the sea at bay...they were looking at their watches and adding to the barrier...then the tide stopped coming in and started to ebb ...they had a tide times booklet and were seeing if it worked... it did! they were still there when we left. feeling like King Canute i shouldn't wonder.
