No need to be embarrassed, sometimes things are just forgotten. I have done the same thing also with My water bill, simply forgot to pay it, which is very odd. I'm the kinda guy Who likes to pay the bills as soon as they come in. Don't know what happened here, I guess since I let it slide the first day or two it just slipped My mind because it wasn't the middle of the month, or when ever it was that it was due.
And here is the kicker at the time I was a Water Plant Operator! Although not for the Utility that was supplying water to the house I lived in. The good part of it is, the house used to have well water, but due to city ordinances and what not, had to hook up to city water & sewer. The well & pump was still functioning and used for irrigation, so with a little snip snip to a garden house and getting two female ends on it I was able to hook the well up to an outside spigot and have water until the next day when I could pay the bill and have them come back out and unlock the meter.
I was tempting just to go out there and do it myself and then relock it before they came out, I had the tools. But that would have been illegal. And would prevent Me from having water hooked back up in My name if I was caught.
