While Sally ordered the pizza, Sharon decided to sneak around and investigate. She started in Sally's bag, before she got off the phone.
Credit cards...in Sally's name. Photo ID...with Sally's picture on it. Pictures of Sharon.
"Pictures..." that was what she needed. Proof somethign was wrong. She put the bag down and went to the table in the corner where she kept all the family photos.
There was her blowing out candles on a birthday cake. A nice picture of Sally and her father...with her father covered up by another picture(but his hand was still visible).
Sharon needed a plan to convince Sally things were wrong. But she needed proof. Kids never believed grownups without proof.
