A glass of cider

A little girl came running into the house bawling her eyes out and
cradling her hand. "Mummy, quick! Get me a glass of cider!" she wailed. "Why
do you want a glass of cider?" asked her mum. "I cut my hand on a thorn, and I
want the pain to go away!"
Confused, but weary of the child's whining, the mother obliged and poured her a glass of cider.
The little girl immediately dunked her hand in it. "Ouch! It still hurts! This cider doesn't work!" she whined. "What are you talking about?" asked her increasingly perplexed parent. "What made you think that cider would ease your pain?" "Well, I overheard my big sister say that whenever she
gets a prick in her hand, she can't wait to get it in cider!"
