Advice On Loving the Homeless?

I need some advice from people that have spent time working with the poor and homeless, and the rich and cranky for that matter.

I took this job at Re-Planet recycling to get to know homeless people. It’s worked, and I can honestly say I have some good relationships with our regulars. However, I can’t help but notice the facts of the matter, that almost all the truly homeless people that I deal with, (which is not necessarily indicative of the problem as a whole) are addicts of one type or another.

Additionally, I get a lot of really rude people, these tend to come in all shapes, sizes and income levels.

Any advice when it comes to loving the homeless?
