Family+Role

I am the family is being the one who is very logical. How i relate to others is by give them my thought on things and what the reality of things is. My fast thinking and quick decision making is what kind of symbolizes my significance in my family. When we are at the store buying food and my mom says oh lets buy this its cheaper and i would normally come back and say no lets buy this because we get more for a lesser price. Then she realizes when we get home that i am right and she was wrong.
