Lol... It's interesting you gave your teacher a tough marking experience. Haha. Imagine what will be in her mind whenever she picks up those essays to write. Lol. She will see all sorts of grammar 😂.
The experience you had in the market was a triangular experience between you, your Mum and the teacher. I can imagine how mischievous you felt after witnessing the scene.
The teacher though. The transition from 4/10 to 2/10 is so hilarious. She's an immovable rock 😂
