Expanding the house

Well tonight my sister had her teen birthday. I cannot believe this is even happening. She is only a few days younger then the twins but my mom said this was her last child. 3 girls and no boys. I suppose it's good that her and the twins will be at college together for a bit so they can get to know each other better. I am almost 55 I can't believe it. Once the twins leave for school we are getting a slightly bigger house. Trevor is older so we are going to let him inherit the house but I am sure Takara will do well for herself with a husband give me some grandchildren as well. I wonder if she will live here or move downtown. Downtown is pricier so she may live here and then move once she has more money too.
