Try and picture them like children. They need your protection, maybe even your help.
I always rush to a midget to pat their head and ask if they are lost. It's a very gratifying feeling to help a fellow human.
Although they are not always receptive, I know the little guys will see my intention was pure and honest when they grow up. Getting through to kids can be difficult. You just need to keep on trying.
Pro tip: get on their level when talking to them, and remain calm, don't raise your voice.
