I have some tests tomorrow, so I should study hard! I’m not very confident about them, but I want to finish them early. I also have a presentation. It is really hard, but I need to do it so that I can feel more relaxed. So, I have to practise my presentation. I’ll do my best! I also have a question: Why do people say “break a leg” with the same meaning as “good luck”? I think this phrase is interesting.
