Now let me tell you what I felt in this poem.
There is so much in nature, and it's realistic. We often thought people, friends, family, money, and love could make us smile as if our hearts were glad, but I think the only thing that can make us and our hearts cherish is how the beauty and laws of nature work without anyone's interference.

I once roamed in my school garden with my best friend. I was texting with somebody when he signaled me to look forward. When I raised my head, I saw a beautiful little sparrow trying to protect her young ones in her nest from the wind. For a while, It felt so arousing that I wondered what charm this little scene contained. I wasn't able to move my eyes away from there.

Truly, nothing is equal to nature.
