Why does he listen to his mum more than me?

Because his mom kept him in her stomach for months then finally gave birth to him. Then breast feeded him for another couple of months then took care of him and brought him up until he is a grown up man that you see today. Thats the reason he and most of other men or women love their moms and listens to them. In most of the cases to their moms more then any other person due to the reason that they value the effort, hard work and time spent for their up bringing.
