I'd rather just get an advance on my next paycheck so I can buy the game right now. Person C: I just got into medical school, but the tuition is really expensive. I need to borrow some money to pay for school, and I'll pay it back after I start working as a doctor. Person D: I don't need to borrow money right now, but I want to have access to money whenever I might need it. It would be nice to be able to pay off some bigger purchases over time.​
