Questions I have for the staff?!?

I have never visit a shelter, so this would be my first time and I am really excited to go there.I have a few questions for the staff that I would love to ask them.

1. How do you got the energy or enthusiasm to help this homeless person everyday?
          I know is a kind of creepy question but it's true. What if one day you are not yourself, you can be angry or just having problems, you would not want to see any one worse than you so you can be very aggressive with the people around you.

2.  Where does this people come from?
         Is that in the whole world there are a lot of homeless people but does this people come from this community or from Vermont, or are they from another part of the country. There are a lot of people who need help even just somewhere to live and have food.

3. Who come you start this organization?
     This is a very big project and you need a lot of courage to make something special like this. Also, you need a motivation for keeping this shelter going and never giving up.
