<prompt> Human: Well, Im a minor idiot.I was buying some stuff at the Gap, and when checking out was offered a pretty good discount for opening a Gap card. I currently have two credit cards, one of which I dont use, the other I pay for everything with and pay in full every month. Now, being the apparently minor idiot I am, I was under the impression that opening a new third credit line can never hurt you and might be able to help, unless you dont pay it off and I had zero intention of even using the card again. I believe I was wrong.I know this has a very minor impact, but for the few bucks of savings I thought it offered, I dont want it to have ANY impact. I dont care about having a Gap card, or thirty bucks, I just thought it wouldnt affect my score unless I abused it.Anyways, had instant regret when I found out about Credit Age being a determining factor in your credit report. It happened like an hour ago and on a non-business-day evening -- is there ANYTHING I can do really quickly to reverse this from even appearing on my report? Maybe I have 24 hours or something? Im sure the hard inquiry will show up Credit Karma already sent me an email about it, but could I somehow make it so that account itself doesnt exist?I called the Gap and I am able to close the account, but they say I cant stop it from having been opened even with only an hour passing. Are they correct?IF I cant get this expunged, what is the best option to turn this to my advantage? Use it a little bit how much? Credit limit on it is 1k and then stop using it after six months? Close it immediately?Help this minor fool!  <response>: Are you buying a house or a car anytime soon? Otherwise, who cares? Its not going to affect you that much.
