i am a first home, and often the first word spoken.

I wield eighteen daggers, yet they are sheathed in velvet. I have a sandpaper kiss, but a voice like a soothing hum. I am a liquid that does not flow, And though I walk with silence, I demand all attention. What am I?

You use me to make most puddings, including a brown betty, but turn me around backwards, and you can pour us on spaghetti.

I'm not saying that I don't talk, but I keep my mouth shut as much as I can. So much so that people use me as an example! I try to be calm, but alas, I'm an anagram.
