Conversation between a cashier and my friends at a sundry shop:

Few days ago,few of my friends asked me...
"Do you have a sis working at ___ ?"
and I was like
"HUH?Fyi I don't really have a sis."
OMG!Who's that creepy girl that admitted she's my sis?I'm so freaking confuse(Totally)!Since when I have one?And as far as i remembered,my family don't have a lost sis!I asked my friends whether they'd taken a picture of her(haha).Unfortunately...nope,not at all.The girl worked at a sundry shop and...I DON'T REALLY KNOW HER!
The bottom line is,if a person suddenly claimed that she's your sis,how would you feel?Isit...
A. Surprised
B. Happy
C. Scared
D. Terrified
E. No feeling (lol)
