Grandpa, what's a lobby?
Well, when I was young we had a room in our house which was called 'the lobby', it was, in fact a toilet. So lobbying was going to the loo, doing something we don't want everyone to see us doing.
Is that what these politicians have been doing? Just going to the loo! It seems there's an awful fuss being made about it.
They are doing something they don't want people to see.
So someone spied in their loo, then?
In a way, but they have this special lobby which is supposed to be something else.
What is it then?
It's a way of making money.
So how do they make money over going to the loo?
They offer their services in exchange for cash.
It doesn't smell too good.
