Cat got your tongue?

Confidence is a funny thing. My favourite words are funny and interesting, I really do over use them and should start thinking of some good alternatives. But until then, it's a funny thing. Sometimes I can chat away and other times a cat's got my tongue and is playing with it as if it's a mouse and it won't give it back. So, while the cat paws at my tongue, I can sit for an hour in silence while everyone around me airs their views, says things I agree with, things I think are ridiculous, things I'd like to pick up on and argue about, but I can't because that cat has still got my tongue.
     Then there are other times, when the cat throws it in the air and it comes back to me and I say something, and the blood rushes to my cheeks, my arms, my chest, my goddamn forehead, and I'm burning hot. I want to apologise, tell everyone to ignore the colour of my skin, but if I dare do that it turns to a shade of purple, so I struggle through as quick as I can.
     Lots of people who know me would be stumped to hear this coming from my mouth, from which come loud cackles, arguments, jokes, stories. But if the ground I'm on is a tiny bit shaky, the room I'm in, a tiny bit intimidating, the people I'm talking to, a tiny bit posh, the cat runs in, takes my tongue and leaves only the tail and the heart when it's finished.
