<prompt> Human: I have a very controlling family, especially my grandmother. She has ruined quite a few people financially. Ive posted a few things about her in rraisedbynarcissists i. For my 16th birthday she wants to get me a joint savings account with her, I stated that I didnt want one but now shes being really pushy. I havent told my parents because right now Im the only one shes talking to in the family. Could this ruin my credit? What are the dangers?  <response>: If shes already screwed people over in your family financially, dont financially tie yourself to her. If you need a joint account, do it with someone you trust. If you trust your parents, open it with them.
