No one would join because they would spend there hole time deciding what they wanted to be then when they finally decided they would have to find it again!
In my area (Australia) about a month ago a Mum was taking her daughter for a driving test and the duaghter lost control and drove the car into a big ditch. The daughter lived but the Mum was killed instantly. I didn't know them but knew someone that did. I wouldnt be able to live if i killed 1 of my parents
