<prompt> Human: Today I went to a jewelry store to get my girlfriends ring repaired after numerous times of it breaking thats a story for a different day. However, after a while they agreed to order a new ring free of charge and they began the transaction but hit a snag within their system. To make the situation easier through their system they had me open an account at first I didnt realize what it was and I just wanted to get out ASAP and stop the GF from being crazy. But anyway they get to the end of it and tell me I have a credit limit...I just hadnt realized that I had opened a credit line through the store until the very end. I didnt put any money on the actual limit I just opened an account I guessI have a few questions regarding this.Now that I realize what I actually opened would it be wise to close it as soon as possible?I also have to get student loans to fund my next year of college and Im wondering if this would affect it in anyway?Should I be worrying about this or just let it sit? I honestly will never use it so I dont know if I should close the account I realize how stupid this was after the fact but it had just been a really long day and I wanted to get in and out as soon as possible. Im just really worried this may affect my financial situation in some way and I really dont want to set myself back because of a bad day.Any help and advice will be greatly appreciatedEdit: Formatting  <response>: Future tip, since I hear a lot of people think theyre opening regular store loyalty accounts: Anytime youre asked for your social security number and income in a retail store, you are applying for a credit card.
