I think is nice spend time with the family especially on the beach! Make me think when I was child playing with "my pot to build the huge castle" that in theory should resist till the day after (that was the idea) but then was destroyed or from someone else or the waves... then I started being smart and bastard... I was putting inside the castle some stick in the way that if someone else wanted to destroy my castle was getting hurt... and to fight the waves I was creating a moat !!! Great time!
thank you to remind me this @clayop
