Watch the Moment When a Toddler Learns Taking Cookies from Strangers is Wrong

In a video going viral in Korea, watch as a little girl learns the difference between receiving cookies and ice cream from her parents versus receiving cookies and ice cream from a stranger.

An excerpt from the conversation:

Adult: “If a strange man says, ‘Let’s go eat cookies!’ You say…”

Child: “I like that.” (smiles)

Adult: “You have to say ‘No!'”
