This art is one of the collection by 7-year-old artist Chibi.

もっとわたしが小さかったころ、好きなものはぜんぶひとりじめしてた。でも、だれかとわけあいっこすると、その子もうれしいし、わたしもうれしいことに気づいた。「これが大人のかいだんのぼるってことだね」っていったら、ママはニコニコわらってた。

When I was younger, I used to keep all the things I liked to myself. But then I realized that if I shared something with someone, it made that person happy and it made me happy too. When I told my mom, "This is what it means to be a grown-up, isn't it?", she smiled at me.
