He guessed that I did magic too (you can usually tell by the reactions of people if they know magic or not) and we talked a little afterwards. When I said I live in Japan, he started speaking Japanese. He knew some simple phrases in Japanese. Apparently he is going to go to Noda in Japan to train some Japanese martial art (that he is already training here) so he started learning Japanese. I did not ask what martial art he is practicing, but thinking about it now, if he is going to Noda he probably does the same martial art that I got a black belt in a long time ago. A random meeting with many strange coincidences.
