Two stories from two of my roommates. The first was related by an 8th grade language arts teacher.
Teacher: (aloud, at the end of her rope) Lord, please give me patience!
Student: (raises hand)
Teacher: (hopeful) Yes?
Student: Ma'am, did you know when you pray for something like patience, God doesn't give you patience, He gives you an opportunity to be patient. So right now, He's answering your prayer.
And tonight, as she grades geography quizzes, my 3rd grade roommate cried out, both incredulously and triumphantly:
"They DO know where the equator is!"
There's no job quite like teaching.
