Heed the wisdom of the guru kitty!
Though sometimes we talk about how a kitty is so cute we just want to eat it up, I'm not sure I've ever felt so literally compelled to eat a cat's head before. Of course the whiskers would have to go first, I don't want them stuck in my throat.
On the bus in the morning I really don't want to talk to anyone. If I see an acquaintance I'll leave my headphones on and nod a friendly hello and keep to myself. This kitty has got the right idea. A nice little wave but no conversation before coffee.
