Whistling

I know how to whistle. I learned when I was like five. I could barely do it but after practicing and a whole lot of elbow grease I got to where I could whistle louder than my dad. Dad, how loud can you whistle? Yeah. I can whistle louder than that. I can whistle by blowing out or by sucking in. I'm better when I'm sucking in. My brother can whistle and my mom can as well. But I think I'm the best whistler in the house.
