One of the things I value most from my nephews and niece are the way they make me look at things, especially things I already think I know about, from a different perspective. It's so easy to assume that I know what I know, until I spend time with them and they remind me to think about things from an alternate point of view. I absolutely agree that, as you said so well, "As adults, we often fall into ruts, forgetting to question why things are done in a certain way rather than another, just as valid way." Something similar to this ended up on my own love list.

(P.S. Thanks for the shout-out! Now I'm nervous!)
