<prompt> Human: Using a throwaway, but Im 18 and I recently found out that my mom signed herself and I up for a credit card under her account. She just handed me a Capital One platinum credit card with my name on it and she has her own card. She told me that she signed me up so I can use it for gas and to build my credit, but Im not the one that pays off the credit card because we share a balance. Ive never heard of this before when building credit and Im actually pretty mad that she did this without my permission. I dont know her credit situation or debt, but I know that shes buying a new car soon and she told me before that she was going to take a car loan through capital one and I dont want to be involved in that in any way. What canshould I do? I havent called the company to try and take me off whatever she has me signed up for. I assume that she signed me up because she probably has bad credit.  <response>: You are probably just named on her account. Its a pretty common thing parent do for their kids.
