As a kid it's adorable to have a gap in your teeth. But then, because of the shifting in my mouth, I started whistling through it, and as a 32-year-old woman, whistling while you speak in sort of annoying. ↗
The parrot's so funny. He imitates me and I don't even realize he's doing it. I'm walking around the house talking to myself and whistling and the next day he's said something I've said... it's scary you know? ↗
If the pressure is getting to you, whistle. In a barely audible way. It's the best way I know of to let go of tension. Music gets your mind off the situation, and the act of whistling melts the tension out of your body. ↗
