Preference?

So the story starts a couple weeks ago when I was in the choir teacher's office talking to him about tour. One girl that was there at the time said to me "So I hear you got asked to preference." Very confused I said "Did I?" She soon after changed the subject. I dismissed it from my brain and didn't think about it until next period.
I'm sitting in Drama and all of a sudden the TA brings in this huge Men's warehouse bag and hands it to me with this big grin on her face.
So when I got home I opened a bag to find one of those big pinwheel flowers that you stick in your yard with a little card in the middle that said Preference With Me?
The flower was sticking out of a pot that had a bunch of Hershey's assorted chocolate in it. I took it out of the bag and discovered that some of the chocolates had letter's on them. O great a mind game.
45 minutes later I finally figured out that Shelby Barney wanted to go to Preference with me.
I was kind of surprised. I knew Shelby from Footloose but other that that I didn't know her that well. Now I had to answer her so I blew up a bunch of balloons that had star-bursts in them. I put a bunch of pieces of paper in the balloons too. I taped my answer to the bottom of the bag after Krystal suggested it.
I dropped the balloons off at her house and waited till I saw her the next day. Unfortunately she couldn't find my answer. I felt like such a jerk. So I just told her yes right there. So tomorrow I'm going on my first date and I'm freaking out!
