"What about those? I like those darker ones." McCoy pointed to the next pair over, the same style but a much deeper blue, "The lighter ones are nice too if that's what ya want. I'm still gonna get those over there though. An the sparkly ones too."

Don't ask him why. It's a stupid reason he's not even admitting to himself. He also pointed at the glittery, dangly ones. Who would the earrings go to? Probably no one, but he felt impelled to buy them anyway. Whatever Obi-Wan wanted he could have though. McCoy wasn't the one planning to wear them after all!
