Makes me think of one of my personal rules when traveling. If I am needing help, I don't take it from someone who approaches me. I just say, no thank you. If I need help, I pick someone randomly and ask for help. The likelihood that they are a criminal is much less compared to someone who approaches me.

This is also good advice for children.

If you need help, ask, don't wait to be asked.
