Task: Question Answering
Input (English): My parents said it was okay to start dating as long as it was a double date with my older sister who would, in essence chaperon me.  I was embarrassed by this  set up, but it was better than not dating at all.   My sister said we would go see a movie at the local cinema on Saturday at 6PM.  Our parents wanted me home by 11 PM.  On Saturday I was so excited and started getting ready very early.  My sister told me to calm down that i was getting ready way too soon.  So I took off my clothes and put on something different.  Finally the time came to get ready and I was excited again.  We left the house at 4:30 and picked up my friend.  He was so handsome! By 5:00 we were at the ice cream shop where we met up with her boyfriend and had ice cream.  Then we went to the movies. My sisters boyfriend purchased popcorn and sodas for all of us.  We munched, drank and watched the movie.  Once it was over we went to the mall and ate at the food court and went and played video games at the arcade. Around 10 PM we were ready to leave.  My sister kissed her boyfriend goodbye and me and my friend piled back into my sisters car.  She dropped him off at his house about 10:15 and he gave me a peck on the cheek.  My sister raised her eyebrow but didn't say anything.  Around 10:30 we showed up to our house where my mom wanted to know everything that went on.  I was in 7th heaven and told her the entirety of the story.  Except maybe the kiss. 
Question: How many people are going on the date?
Output (English): Four.
