<prompt> Human: This question is mostly about money management. Im currently 19, have my first job. My money management isnt excatly that great. Whenever my co worker saw something expensive and wants to buy, they always say wait until next paycheck. My main confusion is that does that mean they spend all of their paycheck already? Why do they have to wait for the money is theres assuming money saved in their account? So how does the whole money management work?  <response>: Its also possible that theyre waiting until the next paycheck to see if they really want to make that expensive purchase.
