Bubbly

Rosalind is naturally a very happy, energetic person. She often has a smile on her face and her attitude is contagious (it probably helps that she can manipulate others emotions very slightly). She loves talking to people and making friends, and often tends to become a bit overprotective of said friends, almost to the point where it gets to be too much.
Despite that, because she spends so often making sure everyone else is happy and okay, there are times when it becomes too much and she slips into a depressed mood. When that happens to tends to lock herself into a room or hide out somewhere until she can get back to normal.
