You walk into a store to buy groceries. But then you bump into a guy and spill the hot coffee he's holding onto his shirt. He glanced at you, said nothing, and hurriedly took off his shirt in front of you. He then hurriedly walked towards the cold water and immediately poured the cold water on his abs. As for you, you rush to get some toothpaste to give him first aid according to your beliefs. He held your hand and spoke to you in upset tone

"Who brought toothpaste to first aid?"
