Earlier quoted context omitted.
How much money have you lost from your private bank account...?
Oh, come on. Have you never lost a check? Never seen a credit card bill you can't explain? Never had an argument with your spouse over what the $2k at Costco was for? Never gotten a bill and had trouble figuring out if you've paid it or not? Accounting failings happen to all of us. The only people with perfect bank accounts are either (1) accountants themselves or (2) never really bothered to look.
Man, was I grateful for the human considerations built into traditional banking!
