You take control

You decide to use this situation to your advantage. "Mom I'll drive home," It was more of a command than an offer. Your mom, still ashamed at being caught simply nods her head. You start to drive home when your mother breaks her silence, "Honey, what you saw was a mistake, it should have never happen, lets agree to forget this and move on," she sounded hopeful that this might work. Not, you thought to yourself. "Mom shut up." Kathy looks absolutely shocked, she was about to protest when
"Mom, I know dad wouldn't be too pleased about this,"
"Your father would never believe your story," Your mother overconfidently said.
"I had this awesome video on my phone that he would love to see,"
"You wouldn't dare," Your mother warned as she gave you the **** stare.
"I could, and I would, but I can also post this video all over the internet," you said smugly
"Please don't, I will do any thing," Your mother pleaded.
