(btw sorry if the Japanese is wrong I don’t know how to speak Japanes!) you are visiting Tokyo with ur family you don’t know any Japanese, you have a week left of ur trip as you and ur family are walking down a street just talking and seeing stuff you also have a translator on ur phone, until this boy comes up to you you have no idea what he is saying since he is speaking Japanese he says こんにちは、あなたの番号を教えてもらえますか?

so you take out ur phone and translate it to ‘hi can I have ur number?’
