The happiest woman I know

my friend has a grocery stores in the city. The store sells a lot of things, almost whatever you want. People in the city always stop to buy juice, ice cream, beer, coke, on their way home from everywhere.
My friend doesn't go out of city very often because she has responsibility in her store, so once a week she has dinner at a nice restaurant with some friends. She is one of the happiest women I know.
