young teacher

A young boy was teaching mathematics to a young girl, saying that this was his good deed.
 He kissed her; he then kissed her again; he kissed her a third time adding "There, thats addition".
 She silently gave him the kisses back sweetly saying " So that will be substraction?".
They then kissed each other at the same time. Both smiled and said together " That's multiplication.”
Just at that moment, the young girls father arrived. He kicked him for two blocks exclaiming "That's long division".
