Сделайте пересказ ЭТО СРОЧНО ПЖ : It was the weekend and I knew that my wife wasn't going to let me go and play golf with my friends until I finished the job she was asking me to do for weeks. My daughter wanted her stamp collection and as the attic was so unorganised, dusty and full of spiders, neither of them wanted to look. So, now it was my job to first sort, clean and then tidy the attic with the hope of finding the stamps in the process. I really didn't want to do it, but as I really wanted to play golf, I didn't have a choice. I started early hoping to finish by noon. After two hours of hard work, I realised that it wasn't the amount stuff I had to sort out that took time, but finding myself reliving the memories that came with everything. I found that had sentimental value. I spent hours running up and down the stairs, showing the family things, telling the story behind each and every one of them. I found photos of the good old days at school and family holidays. I found my daughter's first teddy bear, most of the pictures she drew at nursery and all my wife's failed attempts at painting. Without realizing it, it was three o'clock and I was nowhere near finished. I have a feeling that by the time I have finished this job, we will still have the same amount of things, but in a cleaner, tidier attic.
