A Primary Teacher explains to her class that she is a Labour Supporter.
She asks her students to raise their hands if they too are Labour Supporters.
Everyone in the class raises their hand except one little girl..
The teacher looks at the girl with surprise and says,"'Mary, why didn't you raise your hand?"
"Because I'm not a Labour Supporter", she replied.
The teacher, still shocked, asked, "Well, if you are not a Labour Supporter, then who are you a Supporter of?"
"I'm a Conservative Supporter, and proud of it", Mary replied.
The teacher could not believe her ears. "Mary, why, pray tell, are you a Conservative Supporter?"
"Because my mum is a Conservative Supporter, and my dad is a Conservative Supporter, so I too am a Conservative Supporter!"
"Well", said the teacher in an obviously annoyed tone, "that is no reason for you to be a Conservative Supporter."
"You don't have to be just like your parents all of the time… What if your mum was a lay-about and your dad was a useless waster, what would you be then?
"Then", Mary smiled, "I'd be a Labour Supporter".
