Перевод текста Colin's dinner Disaster
Last Friday it was my birthday. I usually go out to celebrate, but this year l decided to cook dinner for my friends at home. What a mistake! As soon as l finished work l went straight home to start cooking because the invitations were for 8 o'clok. First of all,l put the chicken in the oven, then l prepared the vegetables. When l finished peeling, dicing and stirring, it was 6:45 pm. I set the table guickly and went upstairs to get dressed / Meanwhile the smell of cooking filled the house. I was downstairs again by 7:30 pm. I took the chicken out of the oven and arranged all the food nicely on the table. When l finished everything, l had just enough time to go and get some flowers. I rushed out of thr house and guickly walked towards the shops. I bought some beautiful roses and was back outside my front door ten minutes later. Suddenly, l realised l didn't my keys! I ren round the house checking windows and doors. No luck! Finally my friends arrived. At 8:00 pm,everything was ready and everybody was there. The only problem was that we were outside the dining room window, Flowers in hand,watching the perfrct birthday meal go cold.
