An example of why we should never make hasty assumptions or inferences and conclusions on the basis of a snippet of information ....
A little girl runs out to the backyard where her father is working, and asks him, "Daddy, what's Sex?"
"OK," he thinks, "this day was bound to come, and I'm not going to let my little princess learn about sex from the streets."
So, he sits her down, and tells her all about the birds and the bees. He tells her about conception, sexual intercourse, sperms and eggs. He tells her about puberty, menstruation, erections, and wet dreams.
Then she asks, "Daddy, what is 'A Couple'?"
And he carries on, "A couple are the two people involved in sex, but this can also be two males or two females which we call homosexual relationships," and he goes on to describe in detail several other topics in the vast arena of sex.
When he was done, he finally asks, "So why did you want to know about 'a couple' and 'Sex'?"
... Came the answer ....
"Oh, mummy said lunch would be ready in a couple of secs..."
