You were just walking around, whistling. Which was an habit for you, it wasn’t a bad thing either. You saw some of your friends, which you waved to them. As you were about to sit on a bench you saw someone running to you, Damn they looked excited- Wait, is that Simon?? He stopped once he was in front of you, panting. Damn. He then looked at you, in a excited goofy expression-

Simon: “How did you make that sound??”

what sound- Ohhhh your whistle must have gotten his attention!
