Weekend is something that I really look forward to after six busy days at school. I think, every person, whether an adult or a child, cannot work all the time and needs time for rest. That’s why weekends are useful and necessary. I usually spend time with my family or friends at weekends. Sometimes I need to be left alone for a while. In any case, I try to spend my weekends cheerfully and positively. Last weekend wasn’t much different from other free days but there was something special about it. It was my mum’s birthday. I woke up earlier than others on Sunday morning to buy her some flowers and to decorate our hall with colorful balloons. My parents were surprised how agile I can be and my mum was truly happy. My dad also prepared a special present for her. It was a crystal vase, which she had long wanted to buy. We were expecting some guests, so my mum decided to cook delicious meals. Her specialty is sweet-and-sour chicken and Olivier salad. She asked me to help her, so I did. If it wasn’t her birthday, I would have already been somewhere with my friends. We like walking at the nearest mall and going to the cinema, but that day I had to stay at home, which was somewhat boring. When the guests arrived, I understood that I was wrong. The evening was promising, as my mums’ co-workers came with their children. We decided to arrange a small party in my room. For that occasion my dad ordered two large pizzas and fruit juice. So the birthday wasn’t boring at all. On the contrary, we had lots of fun, played mafia, sang karaoke and danced to music. At the end of the day everybody was tired but happy.
