Happy cave

Once in your life we have a day when a realazation of entire fullfilment comes to you and makes you happy. We don' t plan it. We don't even remember how did it happen. You just understand it and that's all... I 've got such day already . And it's just mine.
I don' t want to dig up for "why"&"when"or " for how long".I 've already know. I' m lucky to have it)
