lagist - When you know just enough to not get embarrassed in public,

When you know just enough to not get embarrassed in public, even if you're still a total mess under the surface.

I knew enough to not get embarrassed when my teacher asked me a question in front of the class.

I knew the answer, but I still messed up the whole thing.

I knew just enough to not look like a total idiot, but I still got called out.
