If bulbs are lighting in your head, click on the title and leave what they say below.
I start with what you do when writing
Your name isn't in the lighting
Yet inviting you to go,
I smoke, a warning you should know
I'm information sent to ears or screens,
Or I'm the means.
'You start with picking up a pen?'
'That's how any great words are started!'
'Come here and show me!'
