A Difficult Question

Four girls go to school every day by taxi. One day one of the girls says, 

“ There is a test in the morning. Let's get to school late. Then we will not have to take the test. ” 

“ What can we tell the teacher?” one of the girls asks. “ He will be angry. We need a good excuse. " 

The girls think for a few minutes, then one of them says, “ Let's tell him that our taxi has a flat tyre. " 

“ That's a good idea, " the other girls say.
