Whistle

Bright as fire,
Valuable as a friend,
High-pitched voice this thing has,
Knowledge of ways better than you,
Help you read,
Keep the heat,
Strong like steel,
Multi-use tool this thing is,
Save your life with its voice,
Find the way with its eye,
Increase the size of things using its arm,
Help you decide what to wear
Keep you warm also cool
Can go with your key
Can go with your bag
It’s a friend, a help and a great key chain.
