I went on a mission for sea glass and came away so relaxed it didn't hurt to climb the hill back home.
With realising that I was not hearing frogs and an extended amount of time on hands and knees as I searched for sea glass (and gave some walkers the sea glass bug it seemed), I also realised the cyclical nature of that which is glass and that which becomes sea glass.
And of the tactile nature of sand....and grit....and stones....such a soothing hand massage I had as I rubbed my hands thoroughly through the shell grit and pebbles. It's a shame that it was still too cool a spring morning to be taking my boots off and giving my feet the same sort of 'pebble rub therapy'. Can I patent this or has it already been done!??
