I bought a "strength" key to give to a woman that I think of as my "sister." She isn't my biological sister. I met her at work, and she and her family made me part of their family while I was dating her brother for a couple of years. He and I have not been together for about 4 years but they still treat me as though I am a member of the family. She has been through a lot since I've known her and always seems to keep it together. I call her for advice all the time when I need it and she will always be my sister.
