A girl you will like easily, she has great personality and a very kind heart. She values her friendship so much, and tries to maintain every friendship she has. She is hard to find but if you have her in your life, be sure to be her friend. She is perfect in many ways, and love to help people. She is always the most beautiful in a friend group and the one that never gives up.
Friend: Hi have you met her yet? She’s Gillie.

Me: Wow she seems nice
Friend: She’s very kind
Me: No wonder she’s called Gillie
