Girl in a town

She always said she was going to be the most successful girl in the whole town.
She loved to read and loved to ride her bike.
She rode through town stopping to folks she knew.
“I’m going to be the most successful girl in the whole town.”
An outsider stopped the girl on her travels and asked the young lady a question she had never been asked before.
“What is your favoured mixer, coke or lemonade?" To no reply
“What is your favoured mixer, coke or lemonade?" Again no reply
“What is your favoured mixer, coke or lemonade?”
The girl was confused; she did not understand what the outsider was saying.
“I don’t understand what your saying”
“I’ll take you to a place, where you will understand”
There was only one bar in town; it didn’t open till the morning.
They waited.
And waited.
Then waited.
The outsider asked for two whiskey and cokes.
The barman was out of coke and served them lemonade.
