我今天回家得很晚，十点才回家。在上出租汽车的时候我听过一个电台广播节目，我觉得很有意思因为有一个人说普通话，一个人说广东话 (reminds me of when one of the small bosses talks to one of the researchers, he always talks in Cantonese whereas the researcher always talks in Mandarin)。Oh well, had fun swimming again with my dad today, it feels good to exert myself, maybe I should try to time my laps as an incentive to improve.
