<prompt> Human: Hes a nice guy, just old. Hes also a hoarder, seems a little off. Ive asked him several times to please cash the checks. I dont want to be on bad terms with him, so I dont want to threaten anything. However, its very frustrating having 3900 in my bank account that I know isnt actually mine.  <response>: I had a landlord that did this. I started to pay him via money order with him writing me a receipt stating he received it which I then carefully stored. That way in the event he lost the money order it would be on him, not me. I would keep relentlessly nagging and then switch to a money order once he cashes those checks. Just make certain you get a receipt each time.
