Okay, so I grew up in a different era. When I was a kid:
To explain how a girl I dated for about 6 months or a year, and I met; we had common friends and we kept getting introduced at social events. The truth; we met at a traffic light when a car full of girls openly (and loudly) admired my car, and I limped out of the car's passenger side, with my leg in a cast, on crutches and won the heart of the cutest girl in the car, who was an aspiring socialite, (yes, apparently they had those in Toledo.)
How two of my high school teammates ended up in the hospital? They accidentally lost control on a curve, slipping on gravel in a one car accident. What really happened; we were racing and they had been drinking, (just a little) and they lost control, slid into a telephone pole at about a hundred, tore the car in half, behind the front seat, which remained in tact, the driver and passenger sustained concussions and minor injuries, no alcohol test administered, also received help with the accident report on the scene, because the answering officer was a family friend of the passenger.
The bazaar thing about that last story is everyone was convinced that a friend of ours was in the back seat and we were all crying and vomiting and yelling, tripping in fields of nettles and poison ivy, looking desperately for our friend, not wanting to find him, not sure of what we would find; served us right. (Those of us who were stupid enough to put our clothes in the laundry, had mothers that looked at the clothes, and assumed something far different than what happened and grabbed us and hugged us and wept. I still feel bad about this today.)
Here is the point. EVERYBODY has lied like this. Some to a much greater extent. The most honest kid I knew growing up, decided he would be married before he lost his virginity, and so he lied by omission, and then embellished it for attention a little, before he was done. That was the same kind of thing Manti actually did.
I quoted scripture before, I will quote it again, "Let he who has not sinned cast the first stone!"
And if you want to know how this need to lie for acceptance gets started, my earlier post is a good example. I told a story about meeting a fraudulent person on a legitimate dating service, to show how believable things could be, and right away, someone I considered to be a good friend started to make fun of me. Behind my back and to my face! When people can't understand how this can happen it is because they are lying, and forgetting what kind of beasts we all are!
