One evening, a mother called out to her child:
– You should brush your teeth at night, or you will get cavities.
The child replied:
– Yes, I will go brush my teeth right away.
– Good, that’s what a good child of mine would do.
– But on the contrary…
– What do you mean, but what?
– …I will not brush my teeth in the morning.
– OH MY!!!!!!!
