As guests in another's house (it even says in the heading that you are "Guest") it is only good manners that you abide by the rules of the house. If you cannot abide by the rules of the house the time will pass when you cease at being a guest and begin to be a pest. Remember this simple childhood doggerel:

When you roam far from your home be a guest and not a pest.

I am sure they taught deportment in school, if only certian of our number would have stayed awake and availed themselves of it, how wonderful it would have been.
