My children and I always let a mom with kids go ahead of us. We also let older people and younger people and people our age and well, come to think of it...I'm not sure how we ever get out of the store! I know that the person we let go ahead goes onto their next stop and pays it forward. I just watched my teenage son, through the store window from the car, as he let someone go ahead of him. I'm not surprised but am very proud!
