Play sick

As I didn't know how I could get out of my sister O have to play sick but as I step out of the room I eye our mother who already got upstairs.

Mother: "Lisa? What you doing into your brother room? I hope he's already up, he has to leave soon too."

"Oh Mother" I start to answer before noticing my mistake as she looks at me slightly confused as I called her mother, I call her mother most of the time but my sister goes with mom normally as they are closer than I am. "I mean mom... I don't feel so well and... Just asked Michael for an Aspirin" I lie as I try to stand as normal as possible.

Mother: "I see, you aren't even dressed yet" she eyed you sceptical "I'm alright late honey, so get back to bed, I will call you from work" she said as she turns around to take the stairs.

What a close call I think to my as I stand there still barefoot and barely clothed in my sister body in the hallway
