The Check Is A Lie
My ex was selling a computer on Craigslist and almost got caught in one of those scams where they send you a check for a much larger amount and have you cash it and send some of the money back to them. He went as far as to get the check mailed to him and asked me to take him to the bank. I insisted that it was a scam and even looked it up online to show him other examples. He still insisted on going to the bank. When we get there I have him tell the teller the story of how he obtained this check. Of course, the guy says it’s a scam, but even then, he still doubted everyone and I know to this day he still regrets not cashing that check.
