"Lithuanian? Latvian? Estonian?" I asked.
"Estonian," he said. "I'm from Estonia, that's why I ask."
His English was quite good but he did have a faint accent which I would have identified as Russian had he not volunteered that he was Estonian.
I didn't have the heart to tell him it was translated from 馬, so after deciding not to start a conversation about how nice I thought Tallinn was, I thanked him for the information and wished him a nice day.
