So the teacher asks the class to use the word 'contagious' in a sentence.
Little Kelly gets up and says,
"My dad has the flu and it is contagious."
"Very good" says the teacher.
Young Robert gets up and says,
"My mum says that laughter can be contagious."
"Excellent Robert!" replies the teacher.
Little Johnny gets up and says,
"My dad and I were out in the front yard the other day and our neighbour is painting his whole house with a 2" brush. My dad says it's going to take the contagious."
