What was the last thing you did with a purposeful sense of "childlike wonder"?

I was asked this question quite seriously the other day. I mean in have done things with wonder. I recognize a lot of the small details that fill this planet with beauty and grace… But never have I ever tried to purposefully rediscover a whole activity as a new inexperienced and unbiased undeveloped person. But I think it will lead to great appreciation. And renewal.

What do you think? Have you done it? What did it uncover for you?
