There was a big earthquake today. I was relaxing at home when I felt violent shaking and heard a loud noise. My smartphone also sounded an alert, which was quite frightening. Fortunately, the shaking stopped after a short while. I also gave a five-minute presentation at school today. Although I had prepared a script, I hadn't practised much, so I ended up improvising. It made me realise that I want to become better at speaking confidently in front of others, even when I have to improvise.
