These girls are half sisters. They have learned and are still learning about each other daily. Neither of them are my kids, but I raise them as my own. They live with us. Share a room. They play together and get on each others nerves too. I love these girls and my heart has finally quit hurting for the things their moms put them thru. I know that they are well loved at home with me and their dad and they never have to worry about anything. Ever!
