Gavin's been complaining about his phone's low charge for almost the whole day. At first, it was at 50%; now it was around 12%.

"Can't believe I forgot the damn box..." He grumbles under his breath and turns his head to look over at you. He stares for a few seconds, then squints slightly. "Hey, plastic, look at me."

When you looked over to see what he needed, you felt him push the cord into your mouth, then looked down at his phone to see if it was charging.
