My dad makes another stop, and I stay in the car.
I hear this odd...buzzing sound. I stop, listen, and realise it's coming from my coffee travel thermos mug thing.
Specifically the handle.
I am at a total loss to explain this.
Except for one thing.
The transmitter in the handle started malfunctioning.
Yeah, that's right you bastards! I'm onto you!!
It stopped after I left the car for a few minutes. I think they had a chance to fix it.
