Fall like Dominoes

Sister act

So it was a pretty long day. The last 4 periods were alright, though I like 2nd period the best. I come home to the house appearing empty and no one there. The house smelled of axe cologne and Melon scented lamp wax.
I hear my sister laughing up stairs so I walk up there. I open her bedroom door to find her making out with her boyfriend with her top off and his pants undone! "Cathy!" I scream. Her boyfriend or "one of her many boyfriends" get off her doing his pants back and her putting her shirt on. "Don't tell mom!" Cathy's lipstick and hair is ruined as she gets off her bed and slides her flip flop wedges on. "Should I go, Cathy?" Her boyfriend is scratching his head and hesitant wether he should leave. "Well you ca-" "No!" I interrupt her "Stay here, dude. Sorry for interrupting." I feel sorry I walked in and instead of closing the door, stalling for her, I interrupt her and this guy's passionate moment. "No, baby. My parents will be here any minute. Just go I'll see you at school tomorrow." Cathy walks to her boyfriend and kisses him. She walks him down stairs to the door. She throws herself on the sofa checking her phone. "Thanks alot, Christina Melanie Fenly for messing up my game!" Cathy is looking dead at me with a stale sarcastic face. "I'm sorry, Cathianne." "You know what, forget it! He's a douche anyway!" Cathy grabs a peppermint off the table and pops it into her mouth. 10 minutes of full silence passes by before I sit on the small sofa next to the one she's on. "Cathy, how do you get so many boys to fall like dominoes for you?" She turns her cell off and looks at me. She sits up and smirks at me. "Well sis, time to teach you the ropes. I use my power. Let me tell you, Chrissy. Boobs are like a gift, wear a tank top with a push up bra and then, talk to the boys. Use your sense of humour. Boys dig funny chicks. Also Chris, boys are intimidated by smartness. Your problem is your a freaking genius, boys hate when girls are super smart it makes them jealous and they feel stupid. So you have to dumb yourself down around boys." Cathy is looking like she just gave important life advice but she just didn't. I'm looking at her with a phoney grin. She then gets up from the sofa plugging in her earbuds then walking upstairs. My only reaction is WTF!!???? She lowers her standards for boys like this and it pisses me off. But I guess this is just my sister's act.
