Is it terrible that I still owe blockbuster money?
Are you serious? Why do you still owe blockbuster money after all these years?
I had very little money. I forgot to return a movie and the late fees kept adding up.
You made a promise with the company to pay back any late fees or they'll pile up. It is your obligation to no matter what, and it's a bad practice to go against your word because you are showing you are not trustworthy with money and promises.
But I know I can return them quickly and finish paying off my account.
That sounds like a great plan. Make sure to get the movies back as soon as possible, so the fees stop adding up.
