For the background: I am from Europe, but we live in Korea, I still don't speak Korean.

Today on the way to the kindergarten, in the tunnel we have to go through, we were walking slowly behind a grandma. When my 2.5 years old had enough, he screamed at her: '비켜!', which means "Get out of the way!" in Korean.

She turned around smiling and asked him '비켜?'. She was nice and she went out of the way so we could walk faster 🤣.
