Playing in the waves, collecting treasures (we didn't find anything as remotely pretty or interesting as Caroline's collections - I was keeping an eye out for colourful plastic bits! - but looking for chalk stones was fun!), writing messages in the sand.. A breath of fresh air..
(I've grown used to seeing this annoying speck of dust on every single one of my photos.. I sadly can't get rid of it so I try my best to hide it!)
