People need help, favours. It's common for some type of people to receive such requests on a regular basis specially those who are wealthy or involved in social work. It's important that every request be looked into with passion, and compassion. There is a human being and his suffering lying behind every single request. The pain needs to be understood.
Every request needs an answer. Never ignore a request. Because then the person in need will always have hope from you when you do not have intention to fulfil it. When you give hope, make sure you have the fuel to keep the fire burning. Giving false hope is nothing short of deceit. Don't deceive someone in need. Be clear what you can do and what you can't. Either fulfil the need or destroy the hope. Don't give false hope.
Have the courage to refuse than to falsely promise!
