Happy man

Mr. Hamid is 63 years old, he is the cleaner. I always see him put on smile while cleaning.
Yesterday morning I saw him whistling while cleaning car park. I greeted him and conducted the short interview with him. I would like to share it with all of you.
Coolingstar9:" Good morning, Mr. Hamid, you are always so cheerful, can you tell me why? "
Hamid:" Good morning to you. I really enjoy working, it make me happy."
Coolingstar9:" Have you ever thought of retirement?"
Hamid:"No, I work because I want to make myself active both my body and mind, I enjoy interacting with people in the working place. I work from 7.30am to 4.pm daily. After work, I do some gardening work at home like watering plants. At night, I like to read books, watching T.V programmes,etc."
Coolingstar9:" Do you work for living?"
Hamid:" No, I had saved enough for my old age before that."
Coolingstar9:" Mr. Hamid, thanks for the short interview."
