One of the guys asking to write down my information. He made some remark about "giving him everything" so I tried to think of irrelevant stuff to add and ended up writing my Chinese name plus "言語學生". His reaction was "I should know what that says, but it's been so long." I didn't realise he'd taken two semesters of Japanese before. He tried to write out the kana he remembered on the back of the slip and this piqued the interest of another guy at the table, so we ended up giving a quick explanation of the Japanese writing system. Later on, someone asked me how my Chinese course was going and one of the bears pointed out that his co-workers were increasingly Chinese women so he'd been meaning to learn Mandarin.
