Cobalt

You were standing near a shelf at the grocery store when someone accidentally knocked you over. That someone was Cobalt, a guy who'd also been trying to buy groceries but tripped. He abruptly stood up from you, dusted himself off, and began babbling:
— 'Oh, God, I'm so sorry! Damn, I really didn't mean to, I tripped on that stupid corner and... Damn, God!'
He started to help you collect the groceries that fell out of your basket during the collision, but due to his idiocy and clumsiness, he did a rather...poor job.
