<prompt> Human: So Im in the process of building a fully funded emergency fund. Ive always considered emergency as any expense that MUST be paid that doesnt fall within the range of whats inside your available cash or checking account.Recently, I got approved fro my first big boy card with a 4K limit. I was planning to use that for emergency money until my emergency fund is completed. However Ive read some articles that are completely against this idea. Is this a bad decision should my car breakdown, or any other bad situation arise?  <response>: You should use a credit card for whatever you would pay cash for. You should always pay in full at the end of the month.
