My favourite place for rest
My favourite place in our city is our park. It is large and the bigger part of it is an amusement park but there are also a few quiet spots where people can take a walk by the lake or sit on a bench in the shadow of the trees.
When I was a little kid, my family and I often went there at weekends to go on amusement rides and get positive emotions. We also took long walks watching beautiful flower beds and magnificent trees. In autumn this green kingdom turns into a fire palace — it's such an amazing sight! I liked to see my parents' happy faces. I was happy too: mum and dad often bought me popcorn or cotton candy. Now I come to the park with my friends. There is an area for roller skating and skateboarding there — it's our usual meeting place. We tell our news and discuss lots of things or play games on our phones or tablets. By the way, in the park there is a spot where we can charge our phones or other devices for free.
There are a lot of great places in our city, but the park will always be the best for me.
