I think that all people have some happy moments in their life. Some happy moments are very similar for many people but some happy moments can be sporadic.
Happy moments in my life:
meeting my husband, birth of our son, own house, buying of our dog Jenny.
And happiness:
Happiness is lying in my bed and reading book or watching TV.
Happiness is usual coffee with my son in café on Friday afternoon.
Happiness is walking with our dog.
Happiness is going for a dinner with my husband.
Happiness is satidfied family.
