Your bureau is such a mess that while working among all the spread documents,folders,cups with coffee and the lamp you may push the ink-pot and pour the ink all around.The damage on the wood will not be so big because the ink have no chance to go inside and absorb in the wood fibres.It simply will flow into the carpet.In this situation you have to act like in an emergency.It seams strange but go and look for a lemon and salt.Put the dry salt over the ink stain and wait for some seconds to change its color-it will become violet because of the absorbing process.Pour lemon juice over the salt and leave the stain to be absorbed by this substance.After some minutes the stain will disappear.Use a wet cloth to rub the rest from the carpet.But if you were so concentrated in your work and didn't notice that the ink-pot is down on the carpet you will spare more time to manage with the ink stain.Here will help you the salt again but combined with milk.The same procedure but you have to repeat it several times untill the stain vanish.
