How does dirt get in your ear? I don’t mean the wax from inside your head, but the bits of grit (or whatever that is) which finds its way to collect in your outer ear. It can’t just be me, or that my ears are some weird shape. I’m not that abnormal.
Anyway, it would make a good toast. No one would assume you were talking about actual dirt. Everyone would think the dirt was gossip. Tricky that way, isn’t it?
