mother or concierge

Is there any difference between the job description of a concierge and a mother? A concierge/mother is often expected to "achieve the impossible" dealing with any request a guest/child may have, no matter how strange, relying on an extensive list of contacts ! I dont think there is any difference other than one is paid and the other is not.
I rather like the historical evolution of the word, " concierge" evolved from the French "Comte de Cierges", the Keeper of the Candles, who tended to visiting nobles in castles in the medieval era. Where to find such service today ? I suggest you look at www.morethangoodmanners.com for the modern equivalent of your candle keeper, who will tend to all your needs and requirements, ( and even providing the castle and candle as well) offering a service second to none.
