Lord knows I love my sister but it's like she lives to stress me out. she got kicked out of her bf's house with my one year old niece for the second time in less than a month and it's giving me a migraine. How do you be their for someone that doesn't listen and put themselves in predicaments like this. She keeps saying it's not fair, it's not fair but the way I see it the only person with a right to say this is my poor niece. I don't want to cry anymore😫😫💔💔
