<prompt> Human: A check I deposited on 1023 suddenly bounced and was deducted from my bank account on 1120, how is this possible? If the person who wrote it had insufficient funds, wouldnt it have bounced within a few days?  <response>: You definitely need to call your bank about this. I really doubt that it would ever take that long for a check to bounce. My guess is that whoever gave you the check disputed it with their bank or something.
