We've rubbed off on Bob a bit, introducing him to American music and teaching him American colloquialisms. (He said f* the other day, but we can't be held accountable for that one. He learned it from the movies, he told us.) I practice my Mandarin with him, and he practices his English with me. I often ask him (in Mandarin) what he ate for breakfast or lunch that day and every time, he answers (in English), "pork over rice." He may very well be eating pork over rice every day for breakfast and lunch, but I'm hoping our conversation develops into something a bit deeper over time.
Here's Bob, and here's a short video of us with Bob:
