You can do anything for eight weeks, even live on tuna salad.
One summer as an undergrad I decided to go to summer school. My parents were not expecting this and told me that it wasn't in their budget. I could manage without a job (I was taking three classes which was a lot in 8 weeks) if I lived in a dorm but didn't get a meal plan. So I mostly lived on the cheapest canned tuna with packets of relish and mayonnaise that I picked up at the cafeteria in the Union. This was not an ideal diet and I never told my parents that I was doing this but I was determined not to let them think I couldn't manage on my own. Stupid, maybe, but it didn't kill me. Do I still eat tuna salad? Sometimes. But I can afford the relish and mayo now, and even have it on bread. The picture looks nicer than anything I fixed in my dorm room!
