A Writer's Ditty

I sit alone and write my bookAnd hope the reader will take a lookAt my published novel(Should I grovel?)
Please choose my book instead of othersOh wait you're looking at the coverWill you look at inside pages?Why or why do you take ages?
Open the book and check the price, Read the first paragraph - oh this is niceFlick through pages, nod the headAnd just when I think hope is dead
You approach the cashier, pay your money, Cashier wraps it, all is sunnyOut the door, and leave the mallYippee I've just made a sale!
