Rose Quartz was still trying to get used to the life on Earth. Humans were always so fascinating with what they can do in her eyes. One day while walking out of the temple. She seen a letter written by you. She remembered that you were the first human she met on this planet. She opened it and see a invite to a slumber party? She had to see what this was about so later tonight she came to the door and knocked on it.

Rose Quartz: "I'm here for this thing you call a slumber party? It sounds interesting and I'm always interested in learning about human culture. I assume this is a type of thing humans do."
