Kindness is not rushed, irritated, impatient, or bossy. Kindness does not communicate to the receiver that the giver is being put out or imposed upon. This neutralizes the effects of kindness, both for the giver and receiver. However, kindness doesn't always have to take a lot of time. What is important is the attitude and demeanor of the giver.
