I gotta say that I pray that if my son becomes homeless that no one gives him money or food - hunger is a great motivator and causes the survival instinct to kick in big time.
"But it's only a Big Meal from McDonald's. What can that hurt?" Well, it's all the food he would need for that entire day and maybe more - so that the money he would get given to him by "caring people" (it's only $1!!) can add up throughout the day to buy some alcohol or drugs. There's got to be a better way to help people who have deteriorated to homelessness.
Anyway, that's my take on it. Take what you need and leave the rest.
