A nun was teaching her class about Guardian Angels

Nun: God has given every man and woman a guardian angel to protect them from harm. He is with us like our shadow. He eats with us, sleeps with us and wakes up in the morning with us.

Student: Sister, I quite believe in what you said. In my sleep last night, I had fallen from the bed. Now I know that naughty person who pushed me out of my bed.
