He's fluent in English, Mandarin, Cantonese, but (like Melania) it's obvious that he's not a true polyglot. He can say hello-goodbye, say please-and-thank you, or ask where the toilets are in Spanish, German, Korean, Thai, and Japanese. He certainly has a fun and playful attitude about it though and he likes to laugh at his own mistakes... and that makes me love him even more!
