Philosophy group

My friend and I've arranged a philosophy reading group and we're meeting for the first time next week in a wonderful sounding place in Truro that I've never been to before. Our first discussion will be about Seneca, who's some old Greek I'd never come across before either! Should I say that? Should I hide my ignorance and feel ashamed or embarrassed that I know nothing about this person from centuries ago? I don't know; I'm never very good at hiding my ignorance (of which I have much) because I can never manage to keep my mouth shout anyway! But it promises to be a lively and stimulating evening whether I manage to sit quietly or not! I can't wait - I could do with some new ideas...
