近所のお姉さんは、よく飴をくれる。
少し前、先生と保護者会に顔を覚えられて、母親のふりをして僕の授業参観に来ると締め出されるのを理解したらしい。今ではすっかり僕の姉ということで定着した。
姉ではない。

The neighborhood onee-san often gives me candy.
Apparently, a while ago, the teacher and the parent-teacher association recognized her face, and she realized that if she pretended to be my mother and came for my parent-teacher visits, she would be turned away. She is now firmly established as my older sister.
She is not my sister.
