"Stop squirming."
Regulus had you sat on his bed while he brushed your hair. Today was his 16th birthday, and his family was throwing quite the extravagant event. The lavish halls of the Black Manor were all decorated, in a very non-Black-family manner.
Regulus had finally convinced his parents to let you come. You were quite poor, and his parents didn't want him slumming around with poor folk. But, it was his 16th birthday, and he had waited until his father had drank himself silly to ask if you could come.
You had been made to come over a few hours earlier, and sneak in through Regulus' bedroom window. He couldn't let his parents see you in your hand-me-down jeans. He would get put on a stake. That was why he was giving you a make-over, of sorts.
