You have to be very careful to help people maintain their privacy and pride whenever this is an issue. Quite often, the best works are those done quietly and without publicity or fuss. It will help all of us if the community knows who is providing the service in cases where this is both possible and appropriate, though. Publicity can be a way of encouraging the rest of the community to pitch in and support your efforts with more than words alone. People expect a lot of Scouts and Scouting, and many like to see us doing something that helps others.
Uniforms are an easy way to show who is helping.
We were talking with one of the administrators at our son's school. Our conversation ranged over many things, but one that stands out the most was when she told us how hard it is to watch some of the children at lunch on the last day of school for the week, or just before a holiday. They fill up their trays as much as they can, because they are at least certain of eating well for that meal. It connected very much with my wife, because she had an experience while providing a tour for an inner-city class of students. Her organisation provides lunch as part of these facility tours.
