playing with young kids eg nephew and niece. seeing the world through their eyes and their innocent comments makes you rethink your outlook. they take such joy from simple things. encourages you to be silly. had husband doing rolly polly down grass banking, me hop skotch and skipping down street hand in hand singing . best was singing following the leader song, loudly, and all 6 of us did actions, in middle of town. lots of stares and smiles, didnt care.
