In the early 1960's during the summer I usually go to the Olympic swimming pool in Columbus, Ohio, The name Olympic was simply the name of the pool and was for everyone.
One day the pool only had a few people, maybe there was a ball game or something, anyway these seven girls suddenly appeared and started to swim with me, I believe they were actually from the near-by Catholic church, they saw I was alone, and bless their hearts ,they wanted me to have company.
To one of the swimmers I said "Hi, Candy" and unknowst to me, it was her real name. I explain that she reminded me of an another Candy--Candy B, it turn out that other Candy was her daughter. So all is forgiven, and we remain friends.
It seems that everyone has a look-a-like that is amazing in itself, but confusion starts when both look-a-likes both have the same first name---- I myself have a look-a-like and his name is also Stanley.
Imagine someone approaching me and saying "Oh, Hi, Stanley" and I am thinking "(What who is that?)" The only explanation is a look-a like, fortunately our last names are different.
So what's the difference between a look-a-like and a doppelganger? Simply a doppelganger is your exact in every way look-a-like that is often portrayed as a ghost or spirit in science fiction fantasy stories, Even the gait of how a person walks is the same.
Yes, on crime shows a person may disguise themselves and change their voice, but it is usually the gait, how a that person walks, that gives them away. (end)
