There is a german song which is called "Rain and Sea" ("Regen und Meer"). It´s about lovers who are just like ocean and rain... about their differences and their relationship. This song -which made me quite sad these days-inspired me for this shot. (and i had great luck that it started raining, when i was in the lake on friday :P)
So after all... I´m not quit with thinking about it...
by the way, see this: i LOVE this commercial:
