one word~shield

all of her life, she relied on her smile to get what she wanted.

powerful, full of white teeth, framed by friendly dimples, and made charming by a slightly wonky incisor, she used it though most of the day, meeting both friends and those she wasn't sure of, hiding true intentions behind the shield of that smile.

it worked beautifully; giving her access to the best tables, excellent customer service, and allowed her to easily remove from her life those who crossed her, with no one the wiser.
