a few times a year

I was born in a modest family, my father was a fisherman who went to sea a few times a year. My father always left me and my family to make a living in the sea there. Once sailed for almost a week my father didn't go home. The catch is always a problem, if the fish is obtained a little, a little bit of the rupiah that my father gets. But if the sea is friendly, my father can bring a lot of rupiah for the survival of my family. Whereas my mother is a housewife, even though she is a housewife, she is an encouragement for me to be better and my father to be more enthusiastic in earning a living.
