I ' ve decided that I 'd like to buy a house sometime in the fall , so yesterday my mom , my sister and I decided to brave the Pittsburgh drizzle and take a look at a few open houses in the areas and price ranges I ' m considering . I have to say that I was appalled by the behavior of some of the agents at these open houses , and I say that as a former real estate agent myself .

Give answer the following question using evidence from the above passage: Why is the family going outside in the weather ?
The family is looking to buy a house .
