On Japanese and Doraemon

Dad: So what electives do you have so far?
Me: Well, there's Econs and Biz Law. I want Japanese but there's no vacancy!
Dad: What are the chances of you getting Japanese?
Me: People say it's difficult, so some might be dropping it during the Add/Drop period. So I don't know.
Dad: Well, if you get it you'll have an advantage because you watch Doraemon.
Me: -___-
