too lawng ago

Refers to a period of time following an event that is too lengthy for any legal action to be taken.

I never intentionally misbehave, but I know that I still made lots of naive-minded screw-ups as an adolescent. However, now that I'm in my fifties and seeing as how I still have a 100%-clean criminal record, I assume that those accidental-slip-up events during my teenage years were way too lawng ago for me to be concerned about any legal action's ever being taken against me regarding them --- not only would the statute of limitations likely have expired decades ago, but most of the folks who'd been involved in those errors would either have forgotten about them or passed on by this time.
