I had no idea who my big sister was because everyday someone different gave me presents. I was surprised and happy. When I had a little sister, I was making a poster for her in my dorm suite and another pledge walked in. She saw the poster which had my little's name on it. Luckily, there were two pledges with the same name. She looked at me and said, "I knew it!"
"Oh no. Please don't go upstairs!" I begged.
"Why would I go upstairs?" she asked.
"To tell my little sister."
"Oh I thought that it was the other one."
She was so fooled!

lol! My little sister was surprised and happy too.
