Weekends to people mean that people can have two days' rest. They can go out or get together at home.
Everybody spends weekends in his own way. Some people relax themselves by listening to music, reading in libraries or doing sports outdoors. In a word, different people have different relaxations.

I often spend weekends with my family. Sometimes my parents take me to visit our relatives. Sometimes we go swimming or go dancing and sometimes I go to read some instructive books. I often enjoy myself at weekends.
