How to spice things up for a Sophomore... Ooh! Hold her hand!
Last gal I knew who was really in to horse shows that a friend dated was pretty much emotionally unavailable because all of her emotional energy was directed to schoolwork and competition. There really was no place else for anyone in her life romantically until she went to Germany became an alcohol-fueld slut, and quit competing.
Send her to Germany. Were you old enough I'd suggest to get her drunk. However neither of you are of legal drinking age so obviously that is out of the question.
Good luck.
