Imagine you are at a birthday party and your mom wants you to go and say thank you to the birthday kid's mom for inviting you to the party. Your mom is asking you to be an ambassador to her, which means to be friendly and represent your mom's gratitude. An ambassador is someone who represents their home country to another country by being friendly, helpful and respectful. They talk with the people of the foreign country and also share information about their own country. Just like how you may share a toy with your friend at the party, ambassadors also share things like business deals, cultural traditions and maybe even help solve problems between countries. Being an ambassador is a big responsibility and it's important to be polite and respectful, just like your mom would expect you to be at the birthday party.
