Brother's laugh

There are thousands of laughs, each with its own characteristics.
On this day, my brother is sleeping late, and my mother asked me to wake him up. I ran to the bed and touched my brother's neck. The younger brother laughed. He smiled so cute: his eyes seemed to be closed, his mouth was small, and a naive and lovely dimple was presented to me, followed by a crisp and sweet laugh, and I couldn’t help but laugh. . He was squatting over the bed, rushing, not knowing what to wear first.
At noon, my mother told us a joke about the story of a tiger catching a snake. There is such a section: When the tiger saw a Wang Ba climbed to the shore, he said to him: "You thought it was a vest. I don't know you anymore?" At this time, an uncle happened to be wearing a vest from my doorstep, and everyone laughed. My brother’s smile is very different from the last time. This laugh has the meaning of ridicule and surprise, and there is a mysterious feeling. I let go of the facial muscles and laugh, but not so mad, even I admire that laugh. I want to laugh but I can't laugh like that, because I am so quiet, my brother is so cool!
Isn't the smile of the younger brother not lovable? The younger brother laughed so tempting, I was really fascinated by his laughter.
