Light and funny has a more compelling quality when you're younger. But I haven't abandoned the genre: I love falling down I love Lucille Ball. It's just that a lot of those stories revolve around problems that I can't convincingly portray at this age.
The funniest racism is the racism between minorities. It's something you don't see dramatized but almost every minority I know who's my age they have these funny stories about their parents stereotyping other minorities.
