Three in one

You walk through the walls of the house and into the kitchen where you find the mother sat at the kitchen table eating a bowl of cereal with her 18 year old twin children, Rose and Mike.

"So, do you two have anything interesting planned for the day?" The mother asks.

"I've got that job interview at lunch time." Mike says, pouring himself a glass of orange juice.

Their mother chuckles at this. "Of course, how did I forget!" She smiles at her children before turning to her daughter. "What about you Rose?"

Rose just throws a shrug at her mother. "No plans. Just thought I'd relax. Might pop to the mall later." Pausing she turns to her brother. "Don't hog the OJ there."

Nodding at his sister Mike reaches over with the Orange juice and you see your opportunity. A click of your fingers and he slips, the Orange juice missing her glass and pouring off the table straight into the lap of her jeans.
