Motorcycle class

You decide you want to take a motorcycle class, so you sign up for one.  Finally the day has arrived, and you're eager to try something new, even if you're nervous.  But then without warning, your gaze met with a boy.  He was so attractive, but you were so taken.  You two talked, and as the time goes on, you find yourself liking him more and more.  The class is now over, and it's time to part ways forever.  You tell him you'd like to stay in contact through facebook, he instead asks for your number.  What do you do?
