Don't even answer the door. If you get separated from your family while at the mall, go straight to the information desk or nearest security guard so they can page your family over the loud speaker and tell them where they can find you. Don't play with matches because your house, clothes, and toys will burn. Don't kiss animals near their mouth. You can give and get germs from animals like strep throat.
Some animals can die from strep and colds too.
Be careful when around strange dogs. I was running near one at an ice cream shop, and he was on a leash, but he still bit me. His owners were surprised when their dog went to bite me. Luckily, his owners had taken him to get his shots and the dog didn't bite through my skin. He's an Italian Greyhound.
