Your father is without a doubt your most favourite person on earth.
If you have your father by your side, you will be happy automatically. You have no idea (or may be you do) how much you love him. It always amazes me.
You do not want to separate from him even if he is in the bathroom!!! You sometimes go stand besides him and wait for him to pee, or you wait at the door of the bathroom for him to finish and come out!
