Last night, I played pool with a Mexican friend at a bar. I told him near the end of the night that I would come to the restaurant where he works the next day. This morning, he sent me a text message that said "buenos dias amigo." Obviously, I understood this one. I responded with "buenas tardes amigo" (I didn't recieve his message until later). His next message wasn't quite so clear to me: "Donde andas" What does he mean?
