A long, long time age, one of my friends was F2. He got a certification for chef before arrival US. His F1 really liked his food so that he had to cook every day. During week days, he went to libary to study and went back home at about 4:00pm to cook. How they spent their night-time was beyond my knowledgement. The poor guy had to work in weekends to make some money. Alternatively, he gave his F1 a ride for shopping and carried all bags for his LD. Of course, he got half-day off on Sunday so that he could played soccer with other guys. Before his wife graduated from school, he applied a school so that he could get a F1 visa -just in case of his F1 cannot find a job right after school. Luckily, his F1 found job and he was in school for few years to get his degree.
What is you contribution? from when to when in school; when and where to find job; when and where to have a baby; kid education, etc. Then it will much easy to convince others to take their parts of duty.
