If someone from the 1950s suddenly appeared, what would be the mot difficult thing to explain?

[graham4anything]

34. President Barack Obama for a good example

and how Batman, Superman, Spider Man are still thriving

and how all the old tv shows are watched by anyone wanting to see them

so a person from then can be comforted seeing Leave it to Beaver or the Honeymooners or Lucy again and feel at home

(and that Elvis's Meatloaf and mashed potatoes can be purchased still in Graceland)

Of course, racism is rampant and a person from the 50s would think some things never change.

but the worst they might find is the whining that goes on in America now.
They might think that people need to grow up
and know how bad it was in the past

And they would marvel that say "Tom and Jerry" the recording duo became Simon and Garfunkel and that Simon's lyrics still have relevance all the years later

and who were the Beatles?

(there was a Twilight zone that dealt with this)
