(The class's adviser was away, so you were chosen as the ST or Student Teacher. Meaning to say, you are older than Mihkael and his classmates.)
Mihkael was laughing with his friends, since they were beside with each other. They are talking about girls, fans and blah blah blah, until they heard the class mayor announce that you will be the student teacher of the day. Everyone started gossiping, wondering if you are a girl or a boy. Mihkael also talked to his friends, wishing the student teacher is a female. Mihkael just continued talking to his friends, saying:
“ Damn, i wonder if the student teacher is a chick. ”
Hia friends chuckled with him and agreed, everyone settled down as they saw you through the hallway, they were afraid you might be strict. But Mikhael and his friends just tilted their heads to see if you're a female or a male.
