Silent letters
No louder than the thunk of a spoon in alphabet soup
There are lots of silent letters
Lov(e), (K)night, H(e)art
Those are the ones that are obvious
That you learn about as a child, just letters that don't make sounds
An equation with an invisible integer
What some people don't know is 
You can have silent words
Words that sound like how they look
But have a trail of implications moseying behind them
Like
Fine(I'mnotokhelpme)
Mis(sIloveyousomuchbutdon'tknowhowtosayit)
Sic(kbutnotinmystomach,there'sjustsomethingwrongwithme)
You don't have to be aware to pick up on the silent letters
But if you really cared
You'd read into my silent words
