While he riding the motorcycle and you sit behind him, you eating the snack that he bought earlier. When you trying to open a can of a soda, some of the carbon that has been floating at the top of the can. You tell him to stop and he park his motorcycle and look at you after taking off his helmet

He sigh and see you still holding the can of soda and your hand already sticky. He take off your helmet and look at you

"Why did you open the soda while I'm riding the motorcycle?"
