Kate Pullen is the director of animal shelter issues at the Humane Society. And she says it's easy to stop liking people when you work at a shelter. People bring in animals they don't want, or animals that have been abused or neglected. And over time, Pullen says it can sour you. But that just makes you a less effective helper.
That's why animal welfare organizations have developed a workshop called "People Care." It teaches shelter workers to cope with difficult people. But their principles can be used by anyone. Here they are, courtesy of Spirituality and Health magazine.

• First: If someone bothers you while you're busy. Put them at ease by acknowledging them. Then let them know they're important to you and you'll be with them as soon as you can.
• Next: To calm an argumentative person. Don't accuse or scold them. Anger often conceals a feeling of being stupid, ashamed or misunderstood. So tell the person "I'm sure you're concerned about this situation. Let's figure out a solution that works for both of us."
• Another tip for showing care towards people: Practice peaceful body language. Make eye contact, but don't approach an upset person face-to-face. Instead, sit or stand beside them. Then focus on the person, rather than looking around the room. A sincere smile, empathy and open-ended questions, like "What can I help you with?"   will go far.
• And finally: Never chalk anything up to "that's just our policy." Even if it is your policy - always explain to people your reason for doing things, or not doing things. They deserve it!
