Barry the bat was just three months old. (Bats live much shorter lives than human beings, so three months old in bat years is about the same as three years old for human beings.

Sometimes when Barry was sleeping snug upside down in his cave he would wake up suddenly and get afraid of the light. Whenever he became frightened like this, he'd give out a short chirp.

CHRIPPPP!!!!!!!

Mom would come flying over right away, using her sonar to avoid bumping into all the walls of the cave. "Honey, are you all right?" she asked in her lovely high-pitched voice.

"Well, I suddenly woke up, and I'm sort of afraid of the light," replied Barry.
