Floristry sounds exciting. I always wanted to learn!
It would be a great job!

Now your teacher is unnecessary harsh. You were late twice in 6 weeks and she suggests it might not be for you? Did she ask why you are late? Do you enjoy your course? I’d talk to your teacher and explain that you really like the course but having hard time arriving on time because of XYZ. I mean being late regularly is terrible but two times could happen to anyone.

I am a high school teacher and I can’t imagine talking like this to any student. It doesn’t mean it’s ok to be late. But there are other ways to address it! Find it out what’s going on first! Form a connection with a student first! This teacher is going to turn her students off from the course!
