<prompt> Human: Someone unexpectedly paid over 5K into my personal bank account yesterday. After checking my statement to see who it was, I do not recognise the name of the sender, it isnt someone that Im familiar with and after looking online this morning I am unable to find a company or person that matches it.Common sense is telling me to speak to my bank, however, I am broke at the moment and struggling to pay my rent. I cant help but feel the urge to take it.What should I do? Can I get in trouble for using it?  <response>: Its not your money. The bank will notice their mistake, take the money back, and youll owe them anything you spent.
