A letter to a friend Can you have a look at the following letter and correct any mistakes if necessary? Dear Kater! How are you doing? Sorry I haven't written for so long. Last week, on 23rd of April I was on a birthday party with my close friend. My friend and I were decorating the ballroom with balloons. We started decorating at 10 am and finished three hours later. We were very tired but it was interesting experience. The balloons were red, yellow and blue. There were twenty of them. During the party one of the guests broke their leg. It happened while she was dancing. All the guests were terrified and didn't know what to do. Then one of them called for a doctor. It was a terrible view for all of us. Fortunately all ended well. All the participants of the party were satisfied with it. I had fun and, the music was fantastic and the food was delicious. Write soon. See you! Kate
