Book, relax, escape. Reading a book allows you to relax. It's like an escape from the daily hustle and bustle. You can enter different worlds, meet different characters, and forget about your problems for a while. And this can be a very happy experience.
Flower, beauty, joy. Flowers are beautiful. When you see a flower, whether it's in a garden or given to you as a bouquet, it can instantly bring a feeling of joy. The colors, the smell, all contribute to this happy feeling in just these three simple words.
