into the correct order. 1 Iryna: So, how are you doing, Vlad? Iryna: Well, what seems to be the problem? Iryna: Listen, forget about that medicine! I have just the thing to get rid of bad colds. You see, my mum is really into herbal medicine. Viad: Well, to be honest, Iryna, I was feeling great on Saturday, but I started to feel ill Sun- day afternoon. I thought I'd get better, but I feel worse than before. And I'm really worried because I have to give a presentation at school on Friday, so I have to be better by then. Iryna: Ah, come on! Give it a try. You just take some of my mum's herbal tea and drink it four times a day. Believe me. You'll be up and dancing around every time. Vlad: Well, I thought I had the flu, but the doctor said it was just a bad cold. He gave me some medicine to take care of my stuffy nose and fever. I'm supposed to take the medicine three times a day after eating, but it doesn't seem to help. He also told me to stay off my feet for a day or so, but I'm so pusy these days. Vlod: Oh, no thanks. Vlad: Dancing around every time, right? Well, you're et today​
