One Early morning a mother went to her sleeping son and woke him up.

MOM : "Wake up, son. It's time to go to school."
SON : "But why, Mama? I don't want to go to school."
MOM : "Give me two reasons why you don't want to go to school."
SON : "One, all the children hate me. Two, all the teachers hate me."
MOM : "Oh! that's not a reason. Come on, you have to go to school."
SON : "Give me two good reasons WHY I *should* go to school?"
MOM : One, you are FIFTY-TWO years old and should understand your responsibilities. Two, you are the PRINCIPAL of the school !!
