We have a homeless problem in our city also so my husband and I joined a group that feeds them at the park, but it didn't last long. If they don't like the food, or pizza, they are given they toss it in the garbage can or on the ground. Some think we were a short order restaurant. When one wanted to get physical with me, in front of two male volunteers, it was time to give only to charities by check. When I spoke to another volunteer about it she said she goes to food banks to collect food to cook their food requests and enjoys hugging them.
Now, what do I do? If I volunteer at an animal shelter my house will soon be over run since I'm a wimp.
Be good to yourself today and everyday.
