Greatest value in his life

Different people have different values. It depends on a lot of factors.
The main value for my elder brother is a memory of walks with Mom along the alley of his childhood. They lived in a big city and not far from their place there was an alley with roses along the pavement. Roses were bright-red, and he felt their smell and loved it a lot. Sometimes they sat on a bench and read a big book with bright pictures. Mom was very patient and quiet. She worked a lot to provide their living and these walks were their tradition on her days off.
Years passed. He lives at another big city. Mom passed away. Last year there was some kind of a road repair near their house. Some people came, brought big trees and planted them along the road. Then other women came and were working the entire week planting flowers. In spring my brother was coming home from his work and felt that something special happened. It was the smell of roses. The greatest value in his life. Roses that were planted along the alley. Roses of his childhood.
