One cannot always bestow all manner of things upon everybody. To refuse a request for just cause is as praiseworthy as to grant a request that is worthy. It is for this reason that the "no" of some people pleases more than the "yes" of others. A refusal accompanied by sweet words and a civil manner gives more satisfaction to a true heart than a favor given with bad grace.
