A sentence describing a happy atmosphere

1. The cars coming and going on the road, the loud engine sound when starting, the harsh friction sound when braking, and the non-stop horn sound ... make the road on the edge of the street very lively.

2. Look, the street is full of people, and everyone is smiling. Young people walk in the street in groups of three and five. They wore MP3 players, listened to the music and couldn't help singing along with it. Some young people are talking and laughing, and their laughter has been echoing in the street. Old people sit quietly in long chairs with crutches and bathe in the warm sunshine. It's really comfortable! The children are jumping and jumping, especially happy.
