Katsuro burst into laughing at the reaction of the other guy. After a few moments he calmed down again. "My excuses," he said honestly with a smile still on his face. "I was sure that you had seen me approaching you. I was sincerly not my intention to surprise you." He hadn't heard more of the phone call then you would from a guy that has troubles with his girlfriend. It had been quite a while since Katsuro had to laugh that hard. This guy was amusing indeed.
